Information disclosure in Apache Airflow's GET /api/v2/connections/{connection_id} endpoint allows authenticated users with Connection-read permission to retrieve plaintext secrets from the extra JSON blob because the redaction allowlist omitted critical field names such as webhook_url, bearer, and service_key. No active exploitation or public PoC code was identified at the time of analysis; EPSS indicates very low exploitation probability (0.02%). Users should upgrade to apache-airflow 3.2.2 or later.
Unvalidated jarURI handling in Apache Flink Kubernetes Operator exposes authenticated low-privilege users to server-side request forgery and arbitrary file read primitives against the operator pod. Any Kubernetes principal holding Custom Resource create permissions can submit a malicious FlinkSessionJob CR with a crafted jarURI - pointing to local filesystem paths, internal cloud metadata endpoints, link-local addresses, or any backing store reachable through Flink's pluggable filesystem layer - and retrieve that content via the submitted job. No public exploit has been identified at time of analysis, and EPSS sits at 0.01% (3rd percentile), but the confidentiality impact is rated High by NVD given the breadth of accessible internal resources.
Open redirect and server-side request forgery in Apache Shiro's Jakarta EE integration module allow authenticated users to forge the unvalidated shiroSavedRequest cookie, causing the server to issue outbound HTTP GET requests to arbitrary URLs or redirect users to untrusted sites. Affected deployments span Shiro 2.0-alpha through 2.1.0 and 3.0.0-alpha-1, exclusively when the shiro-jakarta-ee module is deployed - a scoped condition that materially limits the attack surface. No public exploit or active exploitation has been identified; EPSS sits at 0.04% (12th percentile), consistent with SSVC exploitation status of 'none'.
Apache Shiro's default session and RememberMe cookie configuration omits the 'Secure' attribute, exposing JSESSIONID and rememberMe tokens to interception on any non-TLS channel in applications running versions 1.0 through 2.1.0 and 3.0.0-alpha-1. Successful exploitation allows an attacker with a network intercept position to capture and replay session or persistent-authentication tokens, fully hijacking an authenticated user's session. No public exploit has been identified and CISA has not listed this in KEV; EPSS at 0.03% (9th percentile) and SSVC exploitation status of 'none' indicate no observed active exploitation, making this primarily a risk in mixed HTTP/HTTPS or network-adjacent threat environments.
Session fixation in Apache Shiro 1.0 through 2.1.0 and 3.0.0-alpha-1 exposes authenticated user sessions to hijacking because the framework's default configuration neither invalidates the pre-existing session nor rotates the session ID upon successful login. An unauthenticated remote attacker who plants a known session token before the victim authenticates can reuse that token post-login to access the victim's authenticated context, resulting in high confidentiality impact to the vulnerable system. No public exploit has been identified at time of analysis; EPSS at 0.04% (13th percentile) and SSVC exploitation status of 'none' both reflect negligible observed exploitation activity.
Malicious JEXL expression injection in Apache Syncope's Derived Schema feature enables privileged information disclosure across administrative roles. An administrator holding entitlements over Derived Schemas can embed a crafted JEXL expression that, when evaluated in the context of another administrator's User read operation, exposes security-sensitive User attributes that would not normally be accessible. Affected versions span three release lines (3.0.x through 3.0.16, 4.0.x through 4.0.5, and 4.1.0); no active exploitation is confirmed (no CISA KEV listing) and the EPSS score of 0.02% places this in the 4th percentile for exploitation probability.
LDAP filter injection in Apache Airflow FAB Auth Manager (apache-airflow-providers-fab < 3.6.4) enables unauthenticated remote attackers to manipulate LDAP query logic by embedding special characters in login credentials, resulting in directory data exfiltration or authentication bypass. The vulnerability is confirmed by source code evidence: the `_search_ldap` and `_ldap_get_nested_groups` methods in `override.py` directly interpolated user-supplied input into LDAP filter strings without sanitization. No public exploit code has been identified at time of analysis and CISA KEV does not list this CVE, but the SSVC framework marks it as automatable, meaning exploitation can be scripted at scale against exposed Airflow instances using LDAP auth.
Cross-site scripting in Apache ECharts before 6.1.0 allows remote unauthenticated attackers to inject and execute arbitrary HTML and JavaScript in a victim's browser via the Lines series tooltip rendering path. When an application uses the Lines series with tooltips enabled, omits a custom tooltip.formatter, and populates series.data[i].name with attacker-influenced data, ECharts passes the raw name string through an innerHTML sink rather than applying the HTML escaping that all other built-in tooltip formatters perform. No public exploit is identified at time of analysis and EPSS is 0.03% (10th percentile), but the GitHub PR fixing this issue includes a working test case demonstrating script execution via a crafted name payload.
XML External Entity injection in Apache CXF's WS-Transfer module exposes SOAP endpoints to server-side file read and internal network probing by unauthenticated remote attackers. The insecure XML parser configuration (CWE-611) affects all 3.x releases before 3.6.11, 4.0.x-4.1.x before 4.1.6, and 4.2.0 before 4.2.1. No public exploit has been identified at time of analysis, EPSS sits at the 8th percentile (0.03%), and CISA SSVC rates exploitation as 'none', placing this squarely in the patch-on-schedule rather than emergency-response category despite the broad network attack vector.
Cross-team secret disclosure in apache-airflow-providers-amazon before 9.28.0 allows an authenticated low-privilege caller without team context to read secrets belonging to other teams by supplying a crafted `conn_id` containing a `/` character that collides with another team's AWS Secrets Manager or SSM Parameter Store path. The flaw exists exclusively in the experimental multi-tenant teams feature and is caused by incorrect authorization (CWE-863): the backend failed to reject team-shaped `conn_id`s when no team context was present. No public exploit exists, CISA has not listed this in KEV, and EPSS sits at 0.03% (8th percentile), reflecting low current exploitation probability given the non-default prerequisite.
Improper Authorization in Apache OFBiz Webtools allows unauthenticated remote attackers to bypass access controls and gain partial read and write access to restricted resources. All OFBiz releases before 24.09.06 are affected. No public exploit code has been identified and the vulnerability is not listed in CISA KEV, though SSVC flags it as automatable - meaning scripted mass-scanning is feasible once a technique is published.
Code injection in Apache OFBiz's email services exposes all versions before 24.09.06 to unauthenticated remote exploitation via CWE-94. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms no authentication or special configuration is required, and SSVC classifies the attack as automatable - meaning it can be scripted at scale. Despite the RCE tag attached by intelligence sources, CVSS impact metrics are capped at C:L/I:L/A:N and EPSS sits at 0.03% (8th percentile), indicating no public exploitation observed at time of analysis and no CISA KEV listing.
Cross-site scripting in Apache OFBiz before version 24.09.06 allows remote unauthenticated attackers to inject malicious scripts into web pages rendered in victims' browsers, enabling session hijacking, credential theft, or unauthorized ERP actions performed on behalf of the victim. The CVSS scope change (S:C) confirms the injected script escapes the OFBiz application context and executes in the victim's browser security domain. No active exploitation is confirmed - SSVC rates exploitation as 'none,' EPSS sits at 0.03% (8th percentile), and no public exploit code is referenced; however, a vendor-released patch to version 24.09.06 is available and should be applied.
Improper Access Control in Apache OFBiz multi-tenant deployments exposes confidential data across tenant boundaries to unauthenticated remote attackers via a network-accessible flaw (AV:N/PR:N). All versions prior to 24.09.06 are affected, limited to multi-tenant configurations. No active exploitation has been confirmed (not in CISA KEV), and the EPSS score of 0.02% at the 4th percentile indicates very low observed exploitation interest at time of analysis, though the attack is automatable per SSVC assessment.
Improper authentication in Apache OFBiz before version 24.09.06 permits unauthenticated remote attackers to bypass authentication controls and access limited confidential information without valid credentials. The flaw (CWE-287) is exploitable over the network with no privilege or user interaction requirements, affecting all OFBiz deployments on unpatched versions. No public exploit has been identified at time of analysis, and EPSS rates exploitation probability at 0.02%; however, SSVC marks the attack path as automatable, making it a viable candidate for opportunistic scanning campaigns.
Expression Language Injection in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to inject and evaluate EL expressions through unsanitized application inputs, yielding partial confidentiality and integrity impact on the affected system. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation is network-reachable with no authentication or user interaction, and SSVC classifies the attack as automatable - a meaningful signal given OFBiz's historical exposure to EL-class vulnerabilities. However, real-world urgency is moderated by a very low EPSS score (0.03%, 8th percentile), no public exploit code identified, and no active exploitation reported; vendor patch 24.09.06 is available.
Cross-site scripting, path traversal, and code injection vulnerabilities in Apache OFBiz before version 24.09.06 expose unauthenticated network attackers to the ability to inject malicious scripts into web pages rendered by authenticated users, with the scope change (S:C) in the CVSS vector indicating cross-origin impact such as session hijacking. The co-presence of path traversal and code injection primitives alongside XSS suggests potential for chained exploitation beyond a standard reflected XSS attack, though SSVC rates current exploitation as none and EPSS sits at 0.03% (9th percentile), indicating very low real-world exploitation probability at time of analysis. No public exploit code and no active exploitation (KEV) have been identified; vendor-released patch 24.09.06 is available.
Improper input validation in Apache OFBiz before 24.09.06 allows unauthenticated remote attackers to achieve partial confidentiality and integrity impact over the network with no attack complexity or user interaction required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N). SSVC analysis classifies the flaw as automatable with partial technical impact, meaning it is feasible for automated tools to probe and potentially exploit at scale. No active exploitation has been confirmed - EPSS stands at just 0.04% (11th percentile) and the vulnerability is absent from CISA KEV - indicating current real-world exploitation is unlikely despite the broadly accessible attack surface.
Server-side template injection (SSTI) in Apache OFBiz before 24.09.06 allows attackers with access to the Ecommerce Customer security group to inject malicious FreeMarker (FTL) template expressions via Data Resource records, yielding partial information disclosure and content integrity impact. The root cause is that the platform's Ecommerce Customer role carried content management grants by default, exposing the FTL template rendering engine to insufficiently trusted input. No public exploit has been identified at time of analysis and EPSS probability is very low (0.02%, 7th percentile), though SSVC flags the attack path as automatable once an account is obtained.
Path traversal in Apache OFBiz before 24.09.06 exposes unauthenticated remote attackers to file read and limited file write capabilities outside the application's intended directory boundaries. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms this requires no authentication, no user interaction, and no special network position against any internet-exposed OFBiz instance. No public exploit has been identified at time of analysis and EPSS sits at 0.02% (6th percentile), but SSVC flags the attack as automatable - meaning if tooling emerges, mass internet scanning becomes feasible.
Uncontrolled recursion in Apache Commons Configuration 2.2 through 2.14.x allows remote attackers to trigger a denial of service via StackOverflowError when processing YAML configuration files containing cyclic object references. The vulnerability affects any application using the library to parse untrusted YAML input without validation, with CVSS 5.3 (network-accessible, no authentication required) but exceptionally low exploitation probability (EPSS 0.02%, percentile 5%), indicating this is primarily a defensive hardening fix rather than an actively exploited threat.
Timing side-channel in Apache Tomcat's AJP secret comparison exposes the shared AJP connector secret to remote, unauthenticated attackers capable of making precise network timing measurements. The vulnerability, tracked as CWE-208 (Observable Timing Discrepancy), affects all major Tomcat branches from 7.0.0 through current releases prior to the fixed versions, and could allow an attacker to recover the AJP shared secret through repeated probing. No public exploit code exists at time of analysis, EPSS is 0.02%, and CISA SSVC rates exploitation as none - making real-world risk low despite the network-accessible attack vector.
Apache Airflow Elasticsearch provider writes embedded credentials from the `[elasticsearch] host` configuration URL directly into task logs, allowing any user with task-log read permissions to harvest backend authentication credentials. The vulnerability affects Apache Airflow Providers Elasticsearch versions before 6.5.3 and has been patched by stripping userinfo from the host URL before logging. EPSS exploitation probability is low (0.02%, percentile 4%), indicating limited real-world exploitation despite the sensitive nature of credential exposure.
Apache Airflow Providers OpenSearch versions before 1.9.1 leak backend credentials in task logs when the OpenSearch connection host URL embeds credentials in the format `https://user:password@server:9200`. Any user with task-log read permission can extract these credentials from log output. The vulnerability is confirmed patched in version 1.9.1 and later, with an EPSS score of 0.02% indicating low real-world exploitation probability despite the moderate CVSS score.
Apache CloudStack fails to properly validate resource allocation limits due to time-of-check time-of-use race conditions and missing validations, allowing authenticated users to exceed configured account and domain resource quotas and trigger denial of service conditions. Authenticated network attackers can exploit this vulnerability without user interaction to exhaust infrastructure resources. Affected versions prior to 4.20.3.0 and 4.22.0.1 require immediate patching.
Apache CloudStack's MinIO integration fails to clean up bucket access policies when buckets are deleted, enabling previous bucket owners to retain unauthorized access via cached credentials. If another user creates a bucket with the same name, the former owner gains read/write access using their old access keys. CISA has not listed this CVE in KEV, indicating no confirmed widespread exploitation. CVSS 8.0 reflects high impact but requires authenticated access and user interaction (PR:L/UI:R), tempering immediate urgency. Patch available in CloudStack 4.20.3.0 and 4.22.0.1.
Authenticated CloudStack users can hijack volumes from other tenants' backups via the Backup plugin in versions 4.21.0.0 and 4.22.0.0. Attackers with low-privileged authenticated access can restore any user's backup volume and attach it to their own VMs, enabling complete data theft across tenant boundaries in multi-tenant environments. CVSS 8.1 reflects high confidentiality and integrity impact with low attack complexity. EPSS score of 0.01% indicates minimal observed exploitation activity, while SSVC assessment confirms non-automatable, partial technical impact with no known exploitation. Apache released patch version 4.22.0.1 addressing the access control flaw.
Improper access control in the CloudStack Backup plugin allows authenticated users in CloudStack 4.21.0.0 through 4.22.0.0 to create new virtual machines using backups belonging to other users, enabling unauthorized data access and VM provisioning. The vulnerability requires valid CloudStack credentials and access to specific backup-related APIs but carries elevated risk in multi-tenant environments. Vendor-released patch available in CloudStack 4.22.0.1.
Improper authorization logic in the CloudStack Backup plugin allows authenticated users to enumerate backups from any account in the environment across versions 4.21.0.0 through 4.22.0.0. An attacker with valid user credentials can exploit this to gain unauthorized visibility into backup metadata and existence across all accounts, though backup contents remain protected. The vulnerability requires the Backup plugin to be enabled and affects multi-tenant CloudStack environments where account isolation is a critical security boundary.
Path traversal vulnerability in Apache Wicket's FolderUploadsFileManager allows unauthenticated attackers to read arbitrary files or write files outside the intended upload directory by exploiting unsanitized uploadFieldId and clientFileName parameters. Affected versions 8.0.0-8.17.0, 9.0.0-9.22.0, and 10.0.0-10.8.0 are vulnerable to remote file access and modification without authentication or user interaction. Vendor-released patch available in version 10.9.0.
Timing attack against mod_auth_digest in Apache HTTP Server 2.4.66 allows remote unauthenticated attackers to bypass Digest authentication with high attack complexity. The vulnerability exploits measurable timing differences in digest credential validation, enabling credential compromise without valid authentication. Apache has released patched version 2.4.67; no active exploitation has been confirmed, but CISA SSVC framework indicates automatable exploitation is not feasible due to the timing attack's sensitivity requirements.
Null pointer dereference in mod_authn_socache in Apache HTTP Server 2.4.66 and earlier allows unauthenticated remote attackers to crash child processes in caching forward proxy configurations, resulting in denial of service. The vulnerability has CVSS 5.3 (medium) with network accessibility and no authentication required, but is limited to partial availability impact affecting only specific proxy deployments. Vendor-released patch: version 2.4.67.
HTTP response splitting in Apache HTTP Server 2.4.0 through 2.4.66 allows remote attackers to inject arbitrary HTTP headers and content when the server acts as a proxy to untrusted or compromised backend servers, enabling cache poisoning, session fixation, and cross-site scripting attacks. CVSS 6.5 (moderate) with network attack vector, no authentication required, and confirmed automatable exploitation per CISA SSVC framework. Vendor-released patch: version 2.4.67.
Out-of-bounds read in mod_proxy_ajp of Apache HTTP Server through version 2.4.66 allows remote unauthenticated attackers to disclose sensitive information via a crafted AJP protocol request. The vulnerability has a CVSS score of 5.3 (moderate) with no active exploitation confirmed. Upgrade to version 2.4.67 to remediate.
Improper null termination and out-of-bounds read vulnerability in Apache HTTP Server through version 2.4.66 allows remote unauthenticated attackers to trigger information disclosure with low complexity exploitation. The vulnerability has a CVSS score of 5.3 (medium) with network-accessible attack vector and no user interaction required, though technical impact is limited to confidentiality (partial information disclosure). Vendor-released patch: version 2.4.67 addresses the issue.
Server-Side Request Forgery (SSRF) in Apache Neethi allows remote attackers to make arbitrary outbound requests to internal IP addresses and non-HTTP/HTTPS protocols when an application explicitly calls the PolicyReference API to retrieve remote policies. The vulnerability affects all versions before 3.2.2, which restricts URI schemes to HTTP/HTTPS and blocks link-local, multicast, and any-local addresses. No active exploitation has been confirmed at this time.
Apache Airflow's SmtpHook performs STARTTLS upgrades without SSL certificate validation, allowing man-in-the-middle attackers to intercept SMTP credentials. Remote unauthenticated attackers positioned between an Airflow worker and SMTP server can present a self-signed certificate, complete the TLS handshake, and capture login credentials sent after the upgrade. The vulnerability affects apache-airflow-providers-smtp versions 2.0.0 through 2.x and is patched in version 3.0.0 or later. No public exploit code identified at time of analysis, but EPSS score of 0.01% indicates low real-world exploitation probability despite confidentiality impact.
Remote unauthenticated denial of service in Apache Thrift c_glib language bindings (versions before 0.23.0) allows attackers to crash Thrift servers via specially crafted requests triggering 'free(): invalid pointer' fatal errors. CVSS 7.5 (HIGH) with network vector and low complexity. EPSS score is only 0.02% (4th percentile), indicating very low real-world exploitation probability despite theoretical severity. No active exploitation confirmed (not in CISA KEV); no public POC identified at time of analysis. Vendor-released patch: Apache Thrift 0.23.0.
Improper certificate validation in Apache Storm Prometheus Reporter versions 2.6.3 to 2.8.6 allows man-in-the-middle attacks across all TLS connections in the Storm daemon when the skip_tls_validation configuration option is enabled. Enabling this setting for Prometheus PushGateway connections inadvertently downgrades the JVM-wide SSL context, causing all subsequent HTTPS communications (ZooKeeper, Thrift, Netty, UI) to trust arbitrary certificates without validation, enabling interception of cluster state, topology submissions, and administrative credentials. No public exploit code identified at time of analysis, and EPSS scoring of 0.01% reflects the requirement for explicit administrator misconfiguration to trigger the vulnerability.
Apache Storm's TlsTransportPlugin silently assigns the principal CN=ANONYMOUS to unauthenticated TLS clients when client certificate authentication is not enforced - the default configuration - allowing unauthenticated network principals to interact with Storm services wherever the authorizer does not explicitly deny anonymous access. The fail-open behavior stems from suppressing SSLPeerUnverifiedException rather than rejecting the connection, and the condition is logged at debug level only, leaving the bypass invisible in most production monitoring setups. No public exploit has been identified and EPSS is 0.04% (11th percentile), but SSVC rates the vulnerability as automatable with partial technical impact, meaning tooling could systematically probe exposed clusters for permissive authorizer configurations.
Unsafe deserialization in Apache DolphinScheduler RPC module (versions 3.2.0 to 3.3.0) allows authenticated network attackers to achieve remote code execution by injecting malicious class types into StandardRpcRequest messages sent to Master or Worker nodes. The vulnerability requires network access and valid credentials but carries moderate CVSS (6.3) with very low EPSS exploitation probability (0.02%), suggesting limited real-world weaponization despite the dangerous vulnerability class.
Stored XSS in Apache ActiveMQ and Apache ActiveMQ Web allows authenticated attackers to inject malicious HTML into JMS selector fields, which displays when other users browse queues in the web console. Affects ActiveMQ versions before 5.19.6 and 6.0.0 through 6.2.4; ActiveMQ Web before 5.19.6 and 6.0.0 through 6.2.4. The vulnerability requires valid authentication but no user interaction beyond normal queue browsing, and EPSS indicates very low exploitation probability (0.02%) despite the accessible attack vector.
SQL injection in Apache Doris MCP Server versions before 0.6.1 allows unauthenticated remote attackers to execute unintended SQL statements and bypass query validation and access restrictions via improper neutralization in the MCP query execution interface. The vulnerability has a CVSS score of 5.3 (network-accessible, low complexity, no authentication required) but is classified as partial impact (confidentiality only, no integrity or availability impact) and has not been confirmed as actively exploited. A vendor patch is available.
Apache Kafka's NetworkClient component logs entire request and response payloads at DEBUG level, exposing sensitive authentication credentials, delegation tokens, and configuration data in plaintext logs. This affects Kafka versions 0.11.0 through 3.9.1 and 4.0.0 across the broker and client libraries. While DEBUG logging is not enabled by default (INFO is the standard), organizations that enable DEBUG logging for troubleshooting inadvertently create persistent records of authentication material and secrets that can be harvested by local log readers or accessed via log aggregation systems. CVSS 5.3 reflects low network attack surface (requires prior DEBUG enablement), but SSVC rates this as automatable with partial technical impact, suitable for prioritization in environments using centralized logging.
Session fixation and login-CSRF in apache-airflow-providers-keycloak prior to 0.7.0 allows remote attackers without prior authentication to hijack user sessions by delivering a crafted OAuth callback URL, enabling credential theft from stored Airflow connections. The vulnerability stems from missing OAuth 2.0 state parameter validation and lack of PKCE implementation, requiring only user interaction to trick victims into clicking a malicious link. EPSS score of 0.01% suggests minimal real-world exploitation despite moderate CVSS impact rating.
Apache Airflow 3.0.0 through 3.1.x fails to redact secrets stored as nested fields within JSON-formatted variables, allowing authenticated users with variable access to retrieve plaintext sensitive values. This information disclosure vulnerability affects deployments that store credentials or API keys as JSON dictionary structures in Airflow variables. The EPSS score of 0.02% and CVSS 3.7 with high attack complexity reflect limited real-world exploitation likelihood, but the vulnerability poses direct risk to organizations using JSON-structured secrets without additional access controls.

Path traversal vulnerability in Apache PDFBox Examples ExtractEmbeddedFiles tool allows authenticated local users to write files outside intended directories via malicious PDF files when the initial path traversal fix fails to properly validate file path separators. Affects PDFBox 2.0.24-2.0.36 and 3.0.0-3.0.7; CVSS 4.3 with low exploitability (EPSS 0.02%, SSVC automation: no). Patch versions 2.0.37 and 3.0.8 address the issue.
Apache APISIX 2.99.0 through 3.15.0 transmits sensitive log data in cleartext over HTTP when exporting logs to Tencent Cloud CLS, allowing network-based attackers to intercept and read confidential information without authentication. Vendor-released patch: version 3.16.0. EPSS indicates low real-world exploitation probability (0.01%), though the attack vector is unauthenticated and low-complexity, suggesting availability of automated interception tools rather than active targeted exploitation.
Information disclosure in Apache Airflow 3.0.0 through 3.1.x stems from incomplete secret masking and under-documented workload-isolation and JWT-authentication assumptions, allowing sensitive credentials to surface in task logs and role boundaries to be weaker than a Deployment Manager might assume. The fix in 3.2.0 hardens the secrets masker (PR #58662) and formalizes the security model, JWT token authentication, and workload isolation guidance. No public exploit is identified and EPSS is very low (0.04%), making this a hardening/hygiene issue rather than an urgent exploited flaw.
Stored cross-site scripting in Apache Storm UI before 2.8.6 allows authenticated users with topology submission rights to inject malicious HTML/JavaScript via unsanitized component identifiers, stream names, and grouping values in the visualization component. The payload persists in Nimbus and executes in the browser of any administrator viewing the topology visualization, enabling privilege escalation in multi-tenant deployments. EPSS score of 0.04% and SSVC assessment of partial technical impact with no automated exploitation indicate relatively low real-world risk despite the concerning privilege-escalation scenario.
Apache Log4cxx XMLLayout before version 1.7.0 fails to sanitize XML-forbidden characters in log messages, NDC (Nested Diagnostic Context), and MDC (Mapped Diagnostic Context) properties, producing malformed XML that conforming parsers reject with fatal errors. Attackers who can influence logged data can exploit this to suppress individual log records, degrading audit trails and impairing detection of malicious activity. The vulnerability affects all versions prior to 1.7.0 across multiple distri
Apache Log4net versions before 3.3.0 fail to sanitize XML 1.0-forbidden characters in MDC property keys and values, as well as identity fields, causing serialization exceptions that silently drop log events when XmlLayout or XmlLayoutSchemaLog4J are in use. An attacker who can influence these fields can suppress individual audit log records, impairing detection of malicious activity. No public exploit code or active exploitation has been confirmed; patch is available from the vendor.
Apache Log4j JsonTemplateLayout versions up to 2.25.3 generate invalid JSON when logging non-finite floating-point values (NaN, Infinity, -Infinity), violating RFC 8259 and causing downstream log processing systems to fail indexing or reject records. An unauthenticated remote attacker can trigger this by controlling floating-point values in MapMessages logged by vulnerable applications, resulting in data loss or processing failures in log aggregation pipelines. Vendor-released patch: version 2.25.4.
Apache Log4j Core's XmlLayout in versions up to 2.25.3 fails to sanitize XML-forbidden characters, producing malformed XML output when log messages or MDC values contain such characters. The impact varies by StAX implementation: JRE's built-in StAX silently writes invalid XML that conforming parsers reject, potentially causing downstream log-processing systems to drop records; alternative StAX implementations like Woodstox throw exceptions during logging calls, preventing event delivery to the intended appender. No public exploit code or active exploitation has been identified; this is a data integrity and log availability issue rather than a confidentiality or authentication bypass. Patch version 2.25.4 is available from Apache.
Log4j1XmlLayout in Apache Log4j 1-to-Log4j 2 bridge fails to escape XML 1.0-forbidden characters, causing malformed XML output that conforming XML parsers reject with fatal errors. This impacts downstream log processing systems that may drop or fail to index affected log records, affecting organizations using either Log4j1XmlLayout directly in Log4j Core 2 configurations or the deprecated Log4j 1 compatibility layer with XMLLayout. While no active exploitation has been confirmed, the vulnerability has a notable EPSS score and affects information disclosure integrity. Vendor-released patch version 2.25.4 is available.
Apache Log4j Core 2.21.0 through 2.25.3 allows remote log injection via CRLF sequences in Rfc5424Layout due to undocumented renaming of security-relevant configuration attributes (newLineEscape and useTlsMessageFormat). Attackers can inject malicious log entries or downgrade TLS-framed syslog to unframed TCP, compromising log integrity for stream-based syslog services. SyslogAppender users are not affected. CVSS 6.9 indicates medium-to-high severity; EPSS and exploitation signals not available at time of analysis.
Man-in-the-middle attacks are possible in Apache Log4j Core through 2.25.3 when SMTP, Socket, or Syslog appenders use TLS with the verifyHostName attribute configured in the <Ssl> element, because the attribute was silently ignored despite being available since version 2.12.0. This is a regression from an incomplete fix to CVE-2025-68161 that only addressed hostname verification via system property. An attacker with a certificate from a trusted CA can intercept TLS connections. Apache has released patched version 2.25.4 to correct this issue.
CLIENT_CERT authentication bypass in Apache Tomcat allows unauthenticated remote attackers to bypass certificate-based authentication when soft fail is disabled and Foreign Function Memory (FFM) is enabled, affecting Tomcat 9.0.92-9.0.116, 10.1.22-10.1.53, and 11.0.0-M14-11.0.20. The vulnerability has a CVSS score of 6.5 with high confidentiality impact and partial integrity impact; however, the EPSS score of 0.04% (11th percentile) indicates very low real-world exploitation probability, and no public exploit code or confirmed active exploitation has been identified.
Improper input validation in Apache Tomcat allows remote unauthenticated attackers to obtain sensitive information via an incomplete fix of the prior CVE-2025-66614 vulnerability. Affected versions include Tomcat 11.0.15-11.0.19, 10.1.50-10.1.52, and 9.0.113-9.0.115. The CVSS score of 5.3 reflects low confidentiality impact with no integrity or availability impact, and the 0.04% EPSS score indicates minimal real-world exploitation probability at time of analysis with no public exploit code or KEV status confirmed.
Open redirect vulnerability in Apache Tomcat's LoadBalancerDrainingValve allows unauthenticated remote attackers to redirect users to untrusted sites via crafted URLs. Affects Tomcat 11.0.0-M1 through 11.0.18, 10.1.0-M1 through 10.1.52, 9.0.0.M23 through 9.0.115, and 8.5.30 through 8.5.100. The vulnerability requires user interaction (clicking a malicious link) and has low real-world exploitation probability (EPSS 0.01%), with no public exploit code or confirmed active exploitation identified at the time of analysis.
Apache OpenMeetings versions 3.10 through 8.x allow authenticated users to enumerate file and folder metadata across the system through improper access control in web service APIs, exposing file names, IDs, types, and other metadata fields without authorization to access those resources. This affects all Apache OpenMeetings installations from 3.10 before 9.0.0, where any registered user can query arbitrary folder IDs to retrieve metadata listings. The vulnerability requires valid user credentials (low-privilege authenticated access) and poses a moderate information disclosure risk with an EPSS exploitation probability of 0.01% (3rd percentile), indicating minimal real-world exploitation likelihood despite the low attack complexity.
Unauthenticated remote disclosure of database credentials and other sensitive configuration data in Apache DolphinScheduler 3.1.x via overly-permissive Spring Boot Actuator endpoints. The CVSS:3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms network-accessible exploitation without authentication. EPSS score of 0.02% (5th percentile) indicates low current exploitation likelihood despite the critical nature of credential exposure. Vendor patch available in version 3.2.0, with documented configuration-based workaround for organizations unable to upgrade immediately. No public exploit code identified and SSVC framework shows no active exploitation, though the vulnerability is automatable.
Apache Airflow 3.0.0 through 3.1.8 discloses XCom result values to users with only DAG Run read permissions (such as Viewer role), violating the FAB RBAC model that treats XCom as a protected resource. This information disclosure affects authenticated users and allows them to access sensitive execution results they should not be able to view. The vulnerability is not confirmed as actively exploited, and a patch is available in Apache Airflow 3.2.0.
Improper path validation in Apache ActiveMQ Client and Broker allows authenticated users to traverse the classpath via crafted 'key' values in Stomp consumer creation and Web console message browsing operations, potentially enabling information disclosure or chaining with secondary attacks for greater impact. Affects ActiveMQ Client/Broker versions before 5.19.3 and 6.0.0-6.2.1; patch available in 5.19.4 and 6.2.3 (5.19.3/6.2.2 have platform-specific limitations). EPSS score of 0.04% indicates l
Apache Traffic Server versions 9.0.0-9.2.12 and 10.0.0-10.1.1 are vulnerable to HTTP request smuggling through malformed chunked transfer encoding, allowing attackers to bypass security controls and smuggle malicious requests. The vulnerability stems from improper parsing of chunked messages (CWE-444: Inconsistent Interpretation of HTTP Requests) and affects all deployments using these versions as reverse proxies or intermediaries. Apache has released patched versions 9.2.13 and 10.1.2; no public exploit code or active exploitation has been reported at the time of analysis.
Denial of service in Apache Traffic Server 9.0.0-9.2.12 and 10.0.0-10.1.1 caused by improper handling of POST requests that triggers a server crash under specific conditions. The vulnerability affects all instances of the affected versions and requires no authentication or special privileges to exploit. Vendor-released patches are available in versions 9.2.13 and 10.1.2.
Improper certificate validation in Apache Airflow Provider for Databricks versions 1.10.0 through 1.11.x allows unauthenticated attackers to intercept and manipulate traffic between Airflow and Databricks backends via man-in-the-middle attacks, potentially exfiltrating credentials and sensitive workflow data. The provider did not validate SSL/TLS certificates when establishing connections to Databricks, creating a critical trust boundary weakness. Vendor-released patch available in version 1.12.0; no public exploit code or active exploitation confirmed at time of analysis.
An incorrect authorization vulnerability exists in Apache Artemis and Apache ActiveMQ Artemis where the OpenWire protocol fails to properly enforce permission checks when creating non-durable JMS topic subscriptions on non-existent addresses. A user with only 'createDurableQueue' permission but lacking 'createAddress' permission can bypass authorization controls to create temporary addresses that should be denied, circumventing the intended security model when address auto-creation is disabled. This authentication bypass persists until the OpenWire connection closes and the temporary address is cleaned up.
CVE-2026-28563 is a security vulnerability (CVSS 4.3) that allows an authenticated user with only dag dependencies permission. Remediation should follow standard vulnerability management procedures. Vendor patch is available.
CVE-2026-26929 is a security vulnerability (CVSS 6.5). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
This issue affects Apache Spark: before 3.5.7 and 4.0.1.
Apache Livy versions 0.7.0 and 0.8.0 contain an improper input validation vulnerability (CWE-20) that allows authenticated users to bypass file access controls by injecting malicious Spark configuration values when connecting to Apache Spark 3.1 or later. An attacker with access to Livy's REST or JDBC interface can craft requests with arbitrary Spark configuration parameters to gain unauthorized access to files they do not have permissions to read or modify. This vulnerability is of moderate severity (CVSS 6.3) but requires valid authentication and is fixed in version 0.9.0 and later.
Apache Livy versions 0.3.0 through 0.8.x contain a path traversal vulnerability (CWE-22) that allows authenticated attackers to bypass directory restrictions and access files outside intended whitelist boundaries. The vulnerability only manifests when the 'livy.file.local-dir-whitelist' configuration parameter is set to a non-default value, enabling attackers with valid credentials to read, write, or execute arbitrary files on the server. With a CVSS score of 6.3 (moderate severity) reflecting the requirement for authenticated access and limited impact scope, this vulnerability warrants prioritization for organizations using Livy in multi-tenant or untrusted user environments.
Information disclosure in Apache Airflow's GET /api/v2/connections/{connection_id} endpoint allows authenticated users with Connection-read permission to retrieve plaintext secrets from the extra JSON blob because the redaction allowlist omitted critical field names such as webhook_url, bearer, and service_key. No active exploitation or public PoC code was identified at the time of analysis; EPSS indicates very low exploitation probability (0.02%). Users should upgrade to apache-airflow 3.2.2 or later.
Unvalidated jarURI handling in Apache Flink Kubernetes Operator exposes authenticated low-privilege users to server-side request forgery and arbitrary file read primitives against the operator pod. Any Kubernetes principal holding Custom Resource create permissions can submit a malicious FlinkSessionJob CR with a crafted jarURI - pointing to local filesystem paths, internal cloud metadata endpoints, link-local addresses, or any backing store reachable through Flink's pluggable filesystem layer - and retrieve that content via the submitted job. No public exploit has been identified at time of analysis, and EPSS sits at 0.01% (3rd percentile), but the confidentiality impact is rated High by NVD given the breadth of accessible internal resources.
Open redirect and server-side request forgery in Apache Shiro's Jakarta EE integration module allow authenticated users to forge the unvalidated shiroSavedRequest cookie, causing the server to issue outbound HTTP GET requests to arbitrary URLs or redirect users to untrusted sites. Affected deployments span Shiro 2.0-alpha through 2.1.0 and 3.0.0-alpha-1, exclusively when the shiro-jakarta-ee module is deployed - a scoped condition that materially limits the attack surface. No public exploit or active exploitation has been identified; EPSS sits at 0.04% (12th percentile), consistent with SSVC exploitation status of 'none'.
Apache Shiro's default session and RememberMe cookie configuration omits the 'Secure' attribute, exposing JSESSIONID and rememberMe tokens to interception on any non-TLS channel in applications running versions 1.0 through 2.1.0 and 3.0.0-alpha-1. Successful exploitation allows an attacker with a network intercept position to capture and replay session or persistent-authentication tokens, fully hijacking an authenticated user's session. No public exploit has been identified and CISA has not listed this in KEV; EPSS at 0.03% (9th percentile) and SSVC exploitation status of 'none' indicate no observed active exploitation, making this primarily a risk in mixed HTTP/HTTPS or network-adjacent threat environments.
Session fixation in Apache Shiro 1.0 through 2.1.0 and 3.0.0-alpha-1 exposes authenticated user sessions to hijacking because the framework's default configuration neither invalidates the pre-existing session nor rotates the session ID upon successful login. An unauthenticated remote attacker who plants a known session token before the victim authenticates can reuse that token post-login to access the victim's authenticated context, resulting in high confidentiality impact to the vulnerable system. No public exploit has been identified at time of analysis; EPSS at 0.04% (13th percentile) and SSVC exploitation status of 'none' both reflect negligible observed exploitation activity.
Malicious JEXL expression injection in Apache Syncope's Derived Schema feature enables privileged information disclosure across administrative roles. An administrator holding entitlements over Derived Schemas can embed a crafted JEXL expression that, when evaluated in the context of another administrator's User read operation, exposes security-sensitive User attributes that would not normally be accessible. Affected versions span three release lines (3.0.x through 3.0.16, 4.0.x through 4.0.5, and 4.1.0); no active exploitation is confirmed (no CISA KEV listing) and the EPSS score of 0.02% places this in the 4th percentile for exploitation probability.
LDAP filter injection in Apache Airflow FAB Auth Manager (apache-airflow-providers-fab < 3.6.4) enables unauthenticated remote attackers to manipulate LDAP query logic by embedding special characters in login credentials, resulting in directory data exfiltration or authentication bypass. The vulnerability is confirmed by source code evidence: the `_search_ldap` and `_ldap_get_nested_groups` methods in `override.py` directly interpolated user-supplied input into LDAP filter strings without sanitization. No public exploit code has been identified at time of analysis and CISA KEV does not list this CVE, but the SSVC framework marks it as automatable, meaning exploitation can be scripted at scale against exposed Airflow instances using LDAP auth.
Cross-site scripting in Apache ECharts before 6.1.0 allows remote unauthenticated attackers to inject and execute arbitrary HTML and JavaScript in a victim's browser via the Lines series tooltip rendering path. When an application uses the Lines series with tooltips enabled, omits a custom tooltip.formatter, and populates series.data[i].name with attacker-influenced data, ECharts passes the raw name string through an innerHTML sink rather than applying the HTML escaping that all other built-in tooltip formatters perform. No public exploit is identified at time of analysis and EPSS is 0.03% (10th percentile), but the GitHub PR fixing this issue includes a working test case demonstrating script execution via a crafted name payload.
XML External Entity injection in Apache CXF's WS-Transfer module exposes SOAP endpoints to server-side file read and internal network probing by unauthenticated remote attackers. The insecure XML parser configuration (CWE-611) affects all 3.x releases before 3.6.11, 4.0.x-4.1.x before 4.1.6, and 4.2.0 before 4.2.1. No public exploit has been identified at time of analysis, EPSS sits at the 8th percentile (0.03%), and CISA SSVC rates exploitation as 'none', placing this squarely in the patch-on-schedule rather than emergency-response category despite the broad network attack vector.
Cross-team secret disclosure in apache-airflow-providers-amazon before 9.28.0 allows an authenticated low-privilege caller without team context to read secrets belonging to other teams by supplying a crafted `conn_id` containing a `/` character that collides with another team's AWS Secrets Manager or SSM Parameter Store path. The flaw exists exclusively in the experimental multi-tenant teams feature and is caused by incorrect authorization (CWE-863): the backend failed to reject team-shaped `conn_id`s when no team context was present. No public exploit exists, CISA has not listed this in KEV, and EPSS sits at 0.03% (8th percentile), reflecting low current exploitation probability given the non-default prerequisite.
Improper Authorization in Apache OFBiz Webtools allows unauthenticated remote attackers to bypass access controls and gain partial read and write access to restricted resources. All OFBiz releases before 24.09.06 are affected. No public exploit code has been identified and the vulnerability is not listed in CISA KEV, though SSVC flags it as automatable - meaning scripted mass-scanning is feasible once a technique is published.
Code injection in Apache OFBiz's email services exposes all versions before 24.09.06 to unauthenticated remote exploitation via CWE-94. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms no authentication or special configuration is required, and SSVC classifies the attack as automatable - meaning it can be scripted at scale. Despite the RCE tag attached by intelligence sources, CVSS impact metrics are capped at C:L/I:L/A:N and EPSS sits at 0.03% (8th percentile), indicating no public exploitation observed at time of analysis and no CISA KEV listing.
Cross-site scripting in Apache OFBiz before version 24.09.06 allows remote unauthenticated attackers to inject malicious scripts into web pages rendered in victims' browsers, enabling session hijacking, credential theft, or unauthorized ERP actions performed on behalf of the victim. The CVSS scope change (S:C) confirms the injected script escapes the OFBiz application context and executes in the victim's browser security domain. No active exploitation is confirmed - SSVC rates exploitation as 'none,' EPSS sits at 0.03% (8th percentile), and no public exploit code is referenced; however, a vendor-released patch to version 24.09.06 is available and should be applied.
Improper Access Control in Apache OFBiz multi-tenant deployments exposes confidential data across tenant boundaries to unauthenticated remote attackers via a network-accessible flaw (AV:N/PR:N). All versions prior to 24.09.06 are affected, limited to multi-tenant configurations. No active exploitation has been confirmed (not in CISA KEV), and the EPSS score of 0.02% at the 4th percentile indicates very low observed exploitation interest at time of analysis, though the attack is automatable per SSVC assessment.
Improper authentication in Apache OFBiz before version 24.09.06 permits unauthenticated remote attackers to bypass authentication controls and access limited confidential information without valid credentials. The flaw (CWE-287) is exploitable over the network with no privilege or user interaction requirements, affecting all OFBiz deployments on unpatched versions. No public exploit has been identified at time of analysis, and EPSS rates exploitation probability at 0.02%; however, SSVC marks the attack path as automatable, making it a viable candidate for opportunistic scanning campaigns.
Expression Language Injection in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to inject and evaluate EL expressions through unsanitized application inputs, yielding partial confidentiality and integrity impact on the affected system. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation is network-reachable with no authentication or user interaction, and SSVC classifies the attack as automatable - a meaningful signal given OFBiz's historical exposure to EL-class vulnerabilities. However, real-world urgency is moderated by a very low EPSS score (0.03%, 8th percentile), no public exploit code identified, and no active exploitation reported; vendor patch 24.09.06 is available.
Cross-site scripting, path traversal, and code injection vulnerabilities in Apache OFBiz before version 24.09.06 expose unauthenticated network attackers to the ability to inject malicious scripts into web pages rendered by authenticated users, with the scope change (S:C) in the CVSS vector indicating cross-origin impact such as session hijacking. The co-presence of path traversal and code injection primitives alongside XSS suggests potential for chained exploitation beyond a standard reflected XSS attack, though SSVC rates current exploitation as none and EPSS sits at 0.03% (9th percentile), indicating very low real-world exploitation probability at time of analysis. No public exploit code and no active exploitation (KEV) have been identified; vendor-released patch 24.09.06 is available.
Improper input validation in Apache OFBiz before 24.09.06 allows unauthenticated remote attackers to achieve partial confidentiality and integrity impact over the network with no attack complexity or user interaction required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N). SSVC analysis classifies the flaw as automatable with partial technical impact, meaning it is feasible for automated tools to probe and potentially exploit at scale. No active exploitation has been confirmed - EPSS stands at just 0.04% (11th percentile) and the vulnerability is absent from CISA KEV - indicating current real-world exploitation is unlikely despite the broadly accessible attack surface.
Server-side template injection (SSTI) in Apache OFBiz before 24.09.06 allows attackers with access to the Ecommerce Customer security group to inject malicious FreeMarker (FTL) template expressions via Data Resource records, yielding partial information disclosure and content integrity impact. The root cause is that the platform's Ecommerce Customer role carried content management grants by default, exposing the FTL template rendering engine to insufficiently trusted input. No public exploit has been identified at time of analysis and EPSS probability is very low (0.02%, 7th percentile), though SSVC flags the attack path as automatable once an account is obtained.
Path traversal in Apache OFBiz before 24.09.06 exposes unauthenticated remote attackers to file read and limited file write capabilities outside the application's intended directory boundaries. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms this requires no authentication, no user interaction, and no special network position against any internet-exposed OFBiz instance. No public exploit has been identified at time of analysis and EPSS sits at 0.02% (6th percentile), but SSVC flags the attack as automatable - meaning if tooling emerges, mass internet scanning becomes feasible.
Uncontrolled recursion in Apache Commons Configuration 2.2 through 2.14.x allows remote attackers to trigger a denial of service via StackOverflowError when processing YAML configuration files containing cyclic object references. The vulnerability affects any application using the library to parse untrusted YAML input without validation, with CVSS 5.3 (network-accessible, no authentication required) but exceptionally low exploitation probability (EPSS 0.02%, percentile 5%), indicating this is primarily a defensive hardening fix rather than an actively exploited threat.
Timing side-channel in Apache Tomcat's AJP secret comparison exposes the shared AJP connector secret to remote, unauthenticated attackers capable of making precise network timing measurements. The vulnerability, tracked as CWE-208 (Observable Timing Discrepancy), affects all major Tomcat branches from 7.0.0 through current releases prior to the fixed versions, and could allow an attacker to recover the AJP shared secret through repeated probing. No public exploit code exists at time of analysis, EPSS is 0.02%, and CISA SSVC rates exploitation as none - making real-world risk low despite the network-accessible attack vector.
Apache Airflow Elasticsearch provider writes embedded credentials from the `[elasticsearch] host` configuration URL directly into task logs, allowing any user with task-log read permissions to harvest backend authentication credentials. The vulnerability affects Apache Airflow Providers Elasticsearch versions before 6.5.3 and has been patched by stripping userinfo from the host URL before logging. EPSS exploitation probability is low (0.02%, percentile 4%), indicating limited real-world exploitation despite the sensitive nature of credential exposure.
Apache Airflow Providers OpenSearch versions before 1.9.1 leak backend credentials in task logs when the OpenSearch connection host URL embeds credentials in the format `https://user:password@server:9200`. Any user with task-log read permission can extract these credentials from log output. The vulnerability is confirmed patched in version 1.9.1 and later, with an EPSS score of 0.02% indicating low real-world exploitation probability despite the moderate CVSS score.
Apache CloudStack fails to properly validate resource allocation limits due to time-of-check time-of-use race conditions and missing validations, allowing authenticated users to exceed configured account and domain resource quotas and trigger denial of service conditions. Authenticated network attackers can exploit this vulnerability without user interaction to exhaust infrastructure resources. Affected versions prior to 4.20.3.0 and 4.22.0.1 require immediate patching.
Apache CloudStack's MinIO integration fails to clean up bucket access policies when buckets are deleted, enabling previous bucket owners to retain unauthorized access via cached credentials. If another user creates a bucket with the same name, the former owner gains read/write access using their old access keys. CISA has not listed this CVE in KEV, indicating no confirmed widespread exploitation. CVSS 8.0 reflects high impact but requires authenticated access and user interaction (PR:L/UI:R), tempering immediate urgency. Patch available in CloudStack 4.20.3.0 and 4.22.0.1.
Authenticated CloudStack users can hijack volumes from other tenants' backups via the Backup plugin in versions 4.21.0.0 and 4.22.0.0. Attackers with low-privileged authenticated access can restore any user's backup volume and attach it to their own VMs, enabling complete data theft across tenant boundaries in multi-tenant environments. CVSS 8.1 reflects high confidentiality and integrity impact with low attack complexity. EPSS score of 0.01% indicates minimal observed exploitation activity, while SSVC assessment confirms non-automatable, partial technical impact with no known exploitation. Apache released patch version 4.22.0.1 addressing the access control flaw.
Improper access control in the CloudStack Backup plugin allows authenticated users in CloudStack 4.21.0.0 through 4.22.0.0 to create new virtual machines using backups belonging to other users, enabling unauthorized data access and VM provisioning. The vulnerability requires valid CloudStack credentials and access to specific backup-related APIs but carries elevated risk in multi-tenant environments. Vendor-released patch available in CloudStack 4.22.0.1.
Improper authorization logic in the CloudStack Backup plugin allows authenticated users to enumerate backups from any account in the environment across versions 4.21.0.0 through 4.22.0.0. An attacker with valid user credentials can exploit this to gain unauthorized visibility into backup metadata and existence across all accounts, though backup contents remain protected. The vulnerability requires the Backup plugin to be enabled and affects multi-tenant CloudStack environments where account isolation is a critical security boundary.
Path traversal vulnerability in Apache Wicket's FolderUploadsFileManager allows unauthenticated attackers to read arbitrary files or write files outside the intended upload directory by exploiting unsanitized uploadFieldId and clientFileName parameters. Affected versions 8.0.0-8.17.0, 9.0.0-9.22.0, and 10.0.0-10.8.0 are vulnerable to remote file access and modification without authentication or user interaction. Vendor-released patch available in version 10.9.0.
Timing attack against mod_auth_digest in Apache HTTP Server 2.4.66 allows remote unauthenticated attackers to bypass Digest authentication with high attack complexity. The vulnerability exploits measurable timing differences in digest credential validation, enabling credential compromise without valid authentication. Apache has released patched version 2.4.67; no active exploitation has been confirmed, but CISA SSVC framework indicates automatable exploitation is not feasible due to the timing attack's sensitivity requirements.
Null pointer dereference in mod_authn_socache in Apache HTTP Server 2.4.66 and earlier allows unauthenticated remote attackers to crash child processes in caching forward proxy configurations, resulting in denial of service. The vulnerability has CVSS 5.3 (medium) with network accessibility and no authentication required, but is limited to partial availability impact affecting only specific proxy deployments. Vendor-released patch: version 2.4.67.
HTTP response splitting in Apache HTTP Server 2.4.0 through 2.4.66 allows remote attackers to inject arbitrary HTTP headers and content when the server acts as a proxy to untrusted or compromised backend servers, enabling cache poisoning, session fixation, and cross-site scripting attacks. CVSS 6.5 (moderate) with network attack vector, no authentication required, and confirmed automatable exploitation per CISA SSVC framework. Vendor-released patch: version 2.4.67.
Out-of-bounds read in mod_proxy_ajp of Apache HTTP Server through version 2.4.66 allows remote unauthenticated attackers to disclose sensitive information via a crafted AJP protocol request. The vulnerability has a CVSS score of 5.3 (moderate) with no active exploitation confirmed. Upgrade to version 2.4.67 to remediate.
Improper null termination and out-of-bounds read vulnerability in Apache HTTP Server through version 2.4.66 allows remote unauthenticated attackers to trigger information disclosure with low complexity exploitation. The vulnerability has a CVSS score of 5.3 (medium) with network-accessible attack vector and no user interaction required, though technical impact is limited to confidentiality (partial information disclosure). Vendor-released patch: version 2.4.67 addresses the issue.
Server-Side Request Forgery (SSRF) in Apache Neethi allows remote attackers to make arbitrary outbound requests to internal IP addresses and non-HTTP/HTTPS protocols when an application explicitly calls the PolicyReference API to retrieve remote policies. The vulnerability affects all versions before 3.2.2, which restricts URI schemes to HTTP/HTTPS and blocks link-local, multicast, and any-local addresses. No active exploitation has been confirmed at this time.
Apache Airflow's SmtpHook performs STARTTLS upgrades without SSL certificate validation, allowing man-in-the-middle attackers to intercept SMTP credentials. Remote unauthenticated attackers positioned between an Airflow worker and SMTP server can present a self-signed certificate, complete the TLS handshake, and capture login credentials sent after the upgrade. The vulnerability affects apache-airflow-providers-smtp versions 2.0.0 through 2.x and is patched in version 3.0.0 or later. No public exploit code identified at time of analysis, but EPSS score of 0.01% indicates low real-world exploitation probability despite confidentiality impact.
Remote unauthenticated denial of service in Apache Thrift c_glib language bindings (versions before 0.23.0) allows attackers to crash Thrift servers via specially crafted requests triggering 'free(): invalid pointer' fatal errors. CVSS 7.5 (HIGH) with network vector and low complexity. EPSS score is only 0.02% (4th percentile), indicating very low real-world exploitation probability despite theoretical severity. No active exploitation confirmed (not in CISA KEV); no public POC identified at time of analysis. Vendor-released patch: Apache Thrift 0.23.0.
Improper certificate validation in Apache Storm Prometheus Reporter versions 2.6.3 to 2.8.6 allows man-in-the-middle attacks across all TLS connections in the Storm daemon when the skip_tls_validation configuration option is enabled. Enabling this setting for Prometheus PushGateway connections inadvertently downgrades the JVM-wide SSL context, causing all subsequent HTTPS communications (ZooKeeper, Thrift, Netty, UI) to trust arbitrary certificates without validation, enabling interception of cluster state, topology submissions, and administrative credentials. No public exploit code identified at time of analysis, and EPSS scoring of 0.01% reflects the requirement for explicit administrator misconfiguration to trigger the vulnerability.
Apache Storm's TlsTransportPlugin silently assigns the principal CN=ANONYMOUS to unauthenticated TLS clients when client certificate authentication is not enforced - the default configuration - allowing unauthenticated network principals to interact with Storm services wherever the authorizer does not explicitly deny anonymous access. The fail-open behavior stems from suppressing SSLPeerUnverifiedException rather than rejecting the connection, and the condition is logged at debug level only, leaving the bypass invisible in most production monitoring setups. No public exploit has been identified and EPSS is 0.04% (11th percentile), but SSVC rates the vulnerability as automatable with partial technical impact, meaning tooling could systematically probe exposed clusters for permissive authorizer configurations.
Unsafe deserialization in Apache DolphinScheduler RPC module (versions 3.2.0 to 3.3.0) allows authenticated network attackers to achieve remote code execution by injecting malicious class types into StandardRpcRequest messages sent to Master or Worker nodes. The vulnerability requires network access and valid credentials but carries moderate CVSS (6.3) with very low EPSS exploitation probability (0.02%), suggesting limited real-world weaponization despite the dangerous vulnerability class.
Stored XSS in Apache ActiveMQ and Apache ActiveMQ Web allows authenticated attackers to inject malicious HTML into JMS selector fields, which displays when other users browse queues in the web console. Affects ActiveMQ versions before 5.19.6 and 6.0.0 through 6.2.4; ActiveMQ Web before 5.19.6 and 6.0.0 through 6.2.4. The vulnerability requires valid authentication but no user interaction beyond normal queue browsing, and EPSS indicates very low exploitation probability (0.02%) despite the accessible attack vector.
SQL injection in Apache Doris MCP Server versions before 0.6.1 allows unauthenticated remote attackers to execute unintended SQL statements and bypass query validation and access restrictions via improper neutralization in the MCP query execution interface. The vulnerability has a CVSS score of 5.3 (network-accessible, low complexity, no authentication required) but is classified as partial impact (confidentiality only, no integrity or availability impact) and has not been confirmed as actively exploited. A vendor patch is available.
Apache Kafka's NetworkClient component logs entire request and response payloads at DEBUG level, exposing sensitive authentication credentials, delegation tokens, and configuration data in plaintext logs. This affects Kafka versions 0.11.0 through 3.9.1 and 4.0.0 across the broker and client libraries. While DEBUG logging is not enabled by default (INFO is the standard), organizations that enable DEBUG logging for troubleshooting inadvertently create persistent records of authentication material and secrets that can be harvested by local log readers or accessed via log aggregation systems. CVSS 5.3 reflects low network attack surface (requires prior DEBUG enablement), but SSVC rates this as automatable with partial technical impact, suitable for prioritization in environments using centralized logging.
Session fixation and login-CSRF in apache-airflow-providers-keycloak prior to 0.7.0 allows remote attackers without prior authentication to hijack user sessions by delivering a crafted OAuth callback URL, enabling credential theft from stored Airflow connections. The vulnerability stems from missing OAuth 2.0 state parameter validation and lack of PKCE implementation, requiring only user interaction to trick victims into clicking a malicious link. EPSS score of 0.01% suggests minimal real-world exploitation despite moderate CVSS impact rating.
Apache Airflow 3.0.0 through 3.1.x fails to redact secrets stored as nested fields within JSON-formatted variables, allowing authenticated users with variable access to retrieve plaintext sensitive values. This information disclosure vulnerability affects deployments that store credentials or API keys as JSON dictionary structures in Airflow variables. The EPSS score of 0.02% and CVSS 3.7 with high attack complexity reflect limited real-world exploitation likelihood, but the vulnerability poses direct risk to organizations using JSON-structured secrets without additional access controls.

Path traversal vulnerability in Apache PDFBox Examples ExtractEmbeddedFiles tool allows authenticated local users to write files outside intended directories via malicious PDF files when the initial path traversal fix fails to properly validate file path separators. Affects PDFBox 2.0.24-2.0.36 and 3.0.0-3.0.7; CVSS 4.3 with low exploitability (EPSS 0.02%, SSVC automation: no). Patch versions 2.0.37 and 3.0.8 address the issue.
Apache APISIX 2.99.0 through 3.15.0 transmits sensitive log data in cleartext over HTTP when exporting logs to Tencent Cloud CLS, allowing network-based attackers to intercept and read confidential information without authentication. Vendor-released patch: version 3.16.0. EPSS indicates low real-world exploitation probability (0.01%), though the attack vector is unauthenticated and low-complexity, suggesting availability of automated interception tools rather than active targeted exploitation.
Information disclosure in Apache Airflow 3.0.0 through 3.1.x stems from incomplete secret masking and under-documented workload-isolation and JWT-authentication assumptions, allowing sensitive credentials to surface in task logs and role boundaries to be weaker than a Deployment Manager might assume. The fix in 3.2.0 hardens the secrets masker (PR #58662) and formalizes the security model, JWT token authentication, and workload isolation guidance. No public exploit is identified and EPSS is very low (0.04%), making this a hardening/hygiene issue rather than an urgent exploited flaw.
Stored cross-site scripting in Apache Storm UI before 2.8.6 allows authenticated users with topology submission rights to inject malicious HTML/JavaScript via unsanitized component identifiers, stream names, and grouping values in the visualization component. The payload persists in Nimbus and executes in the browser of any administrator viewing the topology visualization, enabling privilege escalation in multi-tenant deployments. EPSS score of 0.04% and SSVC assessment of partial technical impact with no automated exploitation indicate relatively low real-world risk despite the concerning privilege-escalation scenario.
Apache Log4cxx XMLLayout before version 1.7.0 fails to sanitize XML-forbidden characters in log messages, NDC (Nested Diagnostic Context), and MDC (Mapped Diagnostic Context) properties, producing malformed XML that conforming parsers reject with fatal errors. Attackers who can influence logged data can exploit this to suppress individual log records, degrading audit trails and impairing detection of malicious activity. The vulnerability affects all versions prior to 1.7.0 across multiple distri
Apache Log4net versions before 3.3.0 fail to sanitize XML 1.0-forbidden characters in MDC property keys and values, as well as identity fields, causing serialization exceptions that silently drop log events when XmlLayout or XmlLayoutSchemaLog4J are in use. An attacker who can influence these fields can suppress individual audit log records, impairing detection of malicious activity. No public exploit code or active exploitation has been confirmed; patch is available from the vendor.
Apache Log4j JsonTemplateLayout versions up to 2.25.3 generate invalid JSON when logging non-finite floating-point values (NaN, Infinity, -Infinity), violating RFC 8259 and causing downstream log processing systems to fail indexing or reject records. An unauthenticated remote attacker can trigger this by controlling floating-point values in MapMessages logged by vulnerable applications, resulting in data loss or processing failures in log aggregation pipelines. Vendor-released patch: version 2.25.4.
Apache Log4j Core's XmlLayout in versions up to 2.25.3 fails to sanitize XML-forbidden characters, producing malformed XML output when log messages or MDC values contain such characters. The impact varies by StAX implementation: JRE's built-in StAX silently writes invalid XML that conforming parsers reject, potentially causing downstream log-processing systems to drop records; alternative StAX implementations like Woodstox throw exceptions during logging calls, preventing event delivery to the intended appender. No public exploit code or active exploitation has been identified; this is a data integrity and log availability issue rather than a confidentiality or authentication bypass. Patch version 2.25.4 is available from Apache.
Log4j1XmlLayout in Apache Log4j 1-to-Log4j 2 bridge fails to escape XML 1.0-forbidden characters, causing malformed XML output that conforming XML parsers reject with fatal errors. This impacts downstream log processing systems that may drop or fail to index affected log records, affecting organizations using either Log4j1XmlLayout directly in Log4j Core 2 configurations or the deprecated Log4j 1 compatibility layer with XMLLayout. While no active exploitation has been confirmed, the vulnerability has a notable EPSS score and affects information disclosure integrity. Vendor-released patch version 2.25.4 is available.
Apache Log4j Core 2.21.0 through 2.25.3 allows remote log injection via CRLF sequences in Rfc5424Layout due to undocumented renaming of security-relevant configuration attributes (newLineEscape and useTlsMessageFormat). Attackers can inject malicious log entries or downgrade TLS-framed syslog to unframed TCP, compromising log integrity for stream-based syslog services. SyslogAppender users are not affected. CVSS 6.9 indicates medium-to-high severity; EPSS and exploitation signals not available at time of analysis.
Man-in-the-middle attacks are possible in Apache Log4j Core through 2.25.3 when SMTP, Socket, or Syslog appenders use TLS with the verifyHostName attribute configured in the <Ssl> element, because the attribute was silently ignored despite being available since version 2.12.0. This is a regression from an incomplete fix to CVE-2025-68161 that only addressed hostname verification via system property. An attacker with a certificate from a trusted CA can intercept TLS connections. Apache has released patched version 2.25.4 to correct this issue.
CLIENT_CERT authentication bypass in Apache Tomcat allows unauthenticated remote attackers to bypass certificate-based authentication when soft fail is disabled and Foreign Function Memory (FFM) is enabled, affecting Tomcat 9.0.92-9.0.116, 10.1.22-10.1.53, and 11.0.0-M14-11.0.20. The vulnerability has a CVSS score of 6.5 with high confidentiality impact and partial integrity impact; however, the EPSS score of 0.04% (11th percentile) indicates very low real-world exploitation probability, and no public exploit code or confirmed active exploitation has been identified.
Improper input validation in Apache Tomcat allows remote unauthenticated attackers to obtain sensitive information via an incomplete fix of the prior CVE-2025-66614 vulnerability. Affected versions include Tomcat 11.0.15-11.0.19, 10.1.50-10.1.52, and 9.0.113-9.0.115. The CVSS score of 5.3 reflects low confidentiality impact with no integrity or availability impact, and the 0.04% EPSS score indicates minimal real-world exploitation probability at time of analysis with no public exploit code or KEV status confirmed.
Open redirect vulnerability in Apache Tomcat's LoadBalancerDrainingValve allows unauthenticated remote attackers to redirect users to untrusted sites via crafted URLs. Affects Tomcat 11.0.0-M1 through 11.0.18, 10.1.0-M1 through 10.1.52, 9.0.0.M23 through 9.0.115, and 8.5.30 through 8.5.100. The vulnerability requires user interaction (clicking a malicious link) and has low real-world exploitation probability (EPSS 0.01%), with no public exploit code or confirmed active exploitation identified at the time of analysis.
Apache OpenMeetings versions 3.10 through 8.x allow authenticated users to enumerate file and folder metadata across the system through improper access control in web service APIs, exposing file names, IDs, types, and other metadata fields without authorization to access those resources. This affects all Apache OpenMeetings installations from 3.10 before 9.0.0, where any registered user can query arbitrary folder IDs to retrieve metadata listings. The vulnerability requires valid user credentials (low-privilege authenticated access) and poses a moderate information disclosure risk with an EPSS exploitation probability of 0.01% (3rd percentile), indicating minimal real-world exploitation likelihood despite the low attack complexity.
Unauthenticated remote disclosure of database credentials and other sensitive configuration data in Apache DolphinScheduler 3.1.x via overly-permissive Spring Boot Actuator endpoints. The CVSS:3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms network-accessible exploitation without authentication. EPSS score of 0.02% (5th percentile) indicates low current exploitation likelihood despite the critical nature of credential exposure. Vendor patch available in version 3.2.0, with documented configuration-based workaround for organizations unable to upgrade immediately. No public exploit code identified and SSVC framework shows no active exploitation, though the vulnerability is automatable.
Apache Airflow 3.0.0 through 3.1.8 discloses XCom result values to users with only DAG Run read permissions (such as Viewer role), violating the FAB RBAC model that treats XCom as a protected resource. This information disclosure affects authenticated users and allows them to access sensitive execution results they should not be able to view. The vulnerability is not confirmed as actively exploited, and a patch is available in Apache Airflow 3.2.0.
Improper path validation in Apache ActiveMQ Client and Broker allows authenticated users to traverse the classpath via crafted 'key' values in Stomp consumer creation and Web console message browsing operations, potentially enabling information disclosure or chaining with secondary attacks for greater impact. Affects ActiveMQ Client/Broker versions before 5.19.3 and 6.0.0-6.2.1; patch available in 5.19.4 and 6.2.3 (5.19.3/6.2.2 have platform-specific limitations). EPSS score of 0.04% indicates l
Apache Traffic Server versions 9.0.0-9.2.12 and 10.0.0-10.1.1 are vulnerable to HTTP request smuggling through malformed chunked transfer encoding, allowing attackers to bypass security controls and smuggle malicious requests. The vulnerability stems from improper parsing of chunked messages (CWE-444: Inconsistent Interpretation of HTTP Requests) and affects all deployments using these versions as reverse proxies or intermediaries. Apache has released patched versions 9.2.13 and 10.1.2; no public exploit code or active exploitation has been reported at the time of analysis.
Denial of service in Apache Traffic Server 9.0.0-9.2.12 and 10.0.0-10.1.1 caused by improper handling of POST requests that triggers a server crash under specific conditions. The vulnerability affects all instances of the affected versions and requires no authentication or special privileges to exploit. Vendor-released patches are available in versions 9.2.13 and 10.1.2.
Improper certificate validation in Apache Airflow Provider for Databricks versions 1.10.0 through 1.11.x allows unauthenticated attackers to intercept and manipulate traffic between Airflow and Databricks backends via man-in-the-middle attacks, potentially exfiltrating credentials and sensitive workflow data. The provider did not validate SSL/TLS certificates when establishing connections to Databricks, creating a critical trust boundary weakness. Vendor-released patch available in version 1.12.0; no public exploit code or active exploitation confirmed at time of analysis.
An incorrect authorization vulnerability exists in Apache Artemis and Apache ActiveMQ Artemis where the OpenWire protocol fails to properly enforce permission checks when creating non-durable JMS topic subscriptions on non-existent addresses. A user with only 'createDurableQueue' permission but lacking 'createAddress' permission can bypass authorization controls to create temporary addresses that should be denied, circumventing the intended security model when address auto-creation is disabled. This authentication bypass persists until the OpenWire connection closes and the temporary address is cleaned up.
CVE-2026-28563 is a security vulnerability (CVSS 4.3) that allows an authenticated user with only dag dependencies permission. Remediation should follow standard vulnerability management procedures. Vendor patch is available.
CVE-2026-26929 is a security vulnerability (CVSS 6.5). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
This issue affects Apache Spark: before 3.5.7 and 4.0.1.
Apache Livy versions 0.7.0 and 0.8.0 contain an improper input validation vulnerability (CWE-20) that allows authenticated users to bypass file access controls by injecting malicious Spark configuration values when connecting to Apache Spark 3.1 or later. An attacker with access to Livy's REST or JDBC interface can craft requests with arbitrary Spark configuration parameters to gain unauthorized access to files they do not have permissions to read or modify. This vulnerability is of moderate severity (CVSS 6.3) but requires valid authentication and is fixed in version 0.9.0 and later.
Apache Livy versions 0.3.0 through 0.8.x contain a path traversal vulnerability (CWE-22) that allows authenticated attackers to bypass directory restrictions and access files outside intended whitelist boundaries. The vulnerability only manifests when the 'livy.file.local-dir-whitelist' configuration parameter is set to a non-default value, enabling attackers with valid credentials to read, write, or execute arbitrary files on the server. With a CVSS score of 6.3 (moderate severity) reflecting the requirement for authenticated access and limited impact scope, this vulnerability warrants prioritization for organizations using Livy in multi-tenant or untrusted user environments.
