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.
Apache::Session versions through 1.94 for Perl re-creates deleted sessions. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Stack overflow in ParquetSharp versions 18.1.0 through 23.0.0.0 allows remote unauthenticated attackers to cause denial of service by supplying a maliciously crafted Parquet file with a decimal column declaring an unreasonably large width, triggering unbounded stack allocation in the DecimalConverter.ReadDecimal method. This impacts network services that parse untrusted Parquet files. The vulnerability has been patched in version 23.0.0.1.
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.
Cross-site scripting (XSS) vulnerability in Apache Wicket allows unauthenticated remote attackers to inject malicious JavaScript through crafted strings that break out of JavaScript sequence contexts. Affected versions include Wicket 8.0.0-8.17.0, 9.0.0-9.22.0, and 10.0.0-10.8.0. User interaction (e.g., clicking a malicious link) is required for exploitation. EPSS score of 0.03% (8th percentile) indicates low empirical exploitation probability despite network-accessible attack vector.
Apache Thrift versions prior to 0.23.0 are vulnerable to a denial-of-service condition with unspecified attack mechanisms related to CWE-789 (uncontrolled memory allocation). The vulnerability affects multiple language implementations including Rust, Java, and Node.js, and can be triggered remotely without authentication or user interaction, though the technical mechanism remains partially obscured in available disclosures. With EPSS score of 0.02% (percentile 5%), active exploitation appears unlikely despite the low CVSS complexity score.
Quarkus OpenAPI Generator versions before 2.16.0-lts and 2.16.0 (fixed in 2.17.0) send authentication credentials to unintended API endpoints due to overly broad path-parameter regex matching. The generated authentication filter treats OpenAPI path-template placeholders like {param} as .* patterns, allowing a single parameter to consume forward slashes and match multiple distinct operations. This causes bearer tokens, OAuth tokens, API keys, and basic credentials configured for one protected operation to be leaked to different, unprotected operations on the same service when a client invokes them through normal generated-code paths. No public exploit code has been identified, but the vulnerability is trivial to trigger and affects all authentication schemes relying on the shared path-matching logic.
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.
Out-of-bounds read in Apache Thrift C++ JSON deserialization allows remote attackers to leak sensitive information and trigger denial of service via malformed JSON payloads. Affects Apache Thrift versions prior to 0.23.0. The vulnerability has low exploitation probability (EPSS 0.02%) and is not currently listed in CISA KEV, suggesting limited real-world weaponization despite network-accessible attack vector.
Stack overflow in Apache Thrift c_glib dispatch mechanism allows remote attackers to trigger denial of service via crafted network requests. The vulnerability affects Apache Thrift versions prior to 0.23.0 and requires no authentication or user interaction, resulting in application crashes or service unavailability. Patch is available from the vendor.
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.
Apache Airflow versions prior to 3.2.1 allow authenticated users with read access to at least one directed acyclic graph (DAG) to enumerate and discover the names and existence of all other DAGs and assets in the deployment, regardless of their assigned permissions. This information disclosure vulnerability enables privilege escalation reconnaissance by revealing the complete asset topology to users with limited scope authorization. The vulnerability requires valid user credentials but no elevated privileges, and has no known public exploit code at time of analysis.
Apache Airflow versions prior to 3.2.1 fail to enforce per-DAG access control on the /ui/dags endpoint, allowing authenticated users with read access to at least one DAG to retrieve Human-in-the-Loop prompts and full TaskInstance details for DAGs outside their authorized scope. This information disclosure bypasses the intended per-DAG RBAC boundary, exposing operator parameters and task context data to all authenticated users regardless of their assigned DAG permissions.
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.
CRLF injection in HTTP Headers WordPress plugin up to version 1.19.2 allows authenticated administrators to inject arbitrary Apache directives into .htaccess files via unsanitized custom header fields, causing configuration parse errors and potential site-wide denial of service. Attack requires Administrator-level WordPress access and no user interaction. CVSS 5.5 reflects high availability impact (A:H) balanced against high privilege requirements (PR:H).
Roxy-WI versions prior to 8.2.6.4 allow authenticated attackers to read arbitrary files via path traversal in the POST /config/<service>/show API endpoint. The configver parameter is directly concatenated into a file path without proper validation, permitting directory escape sequences (../) to bypass the existing path guard. An authenticated user can exploit this to access sensitive configuration files and other data readable by the web application process.
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.
Apache Airflow 3.0.0 through 3.1.x fails to invalidate JWT tokens at logout, allowing intercepted tokens to remain valid for unauthorized API access. This session management weakness enables replay attacks against the workflow orchestration platform's REST API. No active exploitation confirmed (EPSS 3rd percentile), but SSVC rates as automatable with partial technical impact. Vendor-released patch: Apache Airflow 3.2.0.
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.
Authenticated denial of service via CQL in Apache Cassandra 4.0 through 5.0 allows authenticated users to elevate query latencies by repeatedly changing passwords, disrupting service availability for legitimate users. The vulnerability affects Cassandra 4.0.0-4.0.19, 4.1.0-4.1.10, and 5.0.0-5.0.6. Vendor-released patches are available (4.0.20, 4.1.11, 5.0.7). With an EPSS score of 0.02% (5th percentile), real-world exploitation risk is minimal despite the moderate CVSS score of 6.5, reflecting the requirement for prior authentication and the low likelihood of widespread abuse.
Apache Cassandra 4.0 through 4.0.19 stores cleartext passwords and other sensitive command history in the ~/.cassandra/cqlsh_history file without redaction, allowing local authenticated users to extract credentials via direct file access. Vendor-released patch available in version 4.0.20; exploitation requires local file system access and existing user privileges but poses significant risk in multi-tenant or shared system environments.
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
VA MAX 8.3.4 contains a remote code execution vulnerability that allows authenticated attackers to execute arbitrary commands by injecting shell metacharacters into the mtu_eth0 parameter. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
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.
Apache Artemis before version 2.52.0 contains an authentication bypass vulnerability (CVE-2026-27446) that allows attackers to read all messages exchanged via the broker and inject new messages. KNIME Business Hub, which embeds Apache Artemis, is affected across all versions, though exploitation requires an authenticated user with workflow execution privileges who can register a federated mirror without authenticating to the underlying Artemis instance. While no public exploit code has been disclosed and CVSS scoring is unavailable, the vulnerability represents a significant insider threat with direct impact on message confidentiality and integrity.
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.
Mod_gnutls versions prior to 0.13.0 fail to validate the Extended Key Usage (EKU) extension during client certificate verification, allowing an attacker with a valid certificate issued for a different purpose to improperly authenticate for TLS client certificate-based access. Only Apache HTTPD servers configured to use client certificate authentication (via GnuTLSClientVerify settings other than 'ignore') are affected. The vulnerability enables unauthorized information disclosure through certificate misuse, with a CVSS score of 6.8 reflecting high confidentiality impact but requiring non-trivial attack complexity.
FileRise, a self-hosted web file manager and WebDAV server, contains an unrestricted file upload vulnerability in its WebDAV endpoint that bypasses filename validation controls present in the regular upload path, allowing authenticated attackers to upload executable file types such as .phtml, .php5, and .htaccess. In non-default Apache configurations lacking LocationMatch protection, this enables remote code execution on the underlying web server. The vulnerability affects FileRise versions prior to 3.8.0 and has been patched; no public exploit code or active KEV listing is currently confirmed, but the presence of a GitHub security advisory indicates vendor acknowledgment of the threat.
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.

Performing a manipulation results in use of hard-coded cryptographic key . The attack can be initiated remotely. The complexity of an attack is rather high. The exploitability is reported as difficult. The exploit has been released to the public and may be used for attacks...
Apache PDFBox versions 2.0.24-2.0.35 and 3.0.0-3.0.6 contain a path traversal vulnerability in the ExtractEmbeddedFiles example that allows attackers to write files outside the intended extraction directory by manipulating embedded file names. Organizations that have integrated this example code into production systems are at risk of unauthorized file writes on the host system. No patch is currently available, requiring developers to manually implement path validation to ensure extracted files remain within the designated directory.
AWS Airflow Providers with Auth Manager fail to validate SAML response origins against the actual instance URL, allowing attackers with valid credentials from one instance to authenticate to other instances with potentially different access controls. This cross-instance authentication bypass requires low privileges and network access but does not directly compromise confidentiality or integrity. Users should upgrade to version 9.22.0 or later to remediate this vulnerability.
Airflow Providers Http is affected by improper control of dynamically-managed code resources (CVSS 8.8).
Insecure session ID generation in Apache::Session::Generate::MD5 through 1.94 for Perl.

Apache\ versions up to \ contains a vulnerability that allows attackers to gain access to systems (CVSS 8.2).
Authenticated users in Apache Superset versions before 6.0.0 can execute write operations against PostgreSQL databases configured as read-only by crafting specially formatted SQL statements that evade validation checks. This allows an attacker with SQLLab access to perform unauthorized data modifications despite read-only protections being in place. No patch is currently available for affected versions.
Authenticated users in Apache Superset versions before 6.0.0 can access sensitive user information including password hashes and email addresses through the Tag endpoint API, which improperly exposes user objects without proper field filtering. An attacker with low-privilege credentials (such as Gamma role) can exploit this to retrieve authentication data that should remain hidden. The vulnerability only affects instances with the TAGGING_SYSTEM enabled, which is disabled by default.
Apache Superset before version 6.0.0 contains an authorization bypass in dataset management that allows authenticated users with write access to datasets to circumvent data access controls and query unauthorized information. An attacker can exploit this by modifying the SQL query of existing datasets to access restricted data that their role should not permit. No patch is currently available, leaving affected deployments vulnerable until upgrading to version 6.0.0.
Apache Superset before version 6.0.0 contains a SQL injection vulnerability in the sqlExpression and where parameters that allows authenticated users with read access to extract sensitive data through error-based techniques. An attacker with valid credentials could exploit this to bypass query restrictions and access unauthorized database information. A patch is available in version 6.0.0 and later.
Insufficient SQL function restrictions in Apache Superset before 4.1.2 allow authenticated users to execute sensitive database functions on ClickHouse engines that should have been blocked. An attacker with database access could leverage the incomplete DISALLOWED_SQL_FUNCTIONS list to bypass security controls and potentially extract or manipulate data. No patch is currently available for affected versions of Apache Superset, PostgreSQL, and related deployments.
Airflow versions before 2.11.1 have a vulnerability that allows authenticated users with audit log access to see sensitive values in audit logs which they should not see. When sensitive connection parameters were set via airflow CLI, values of those variables appeared in the audit log and were stored unencrypted in the Airflow database. While this risk is limited to users with audit log access, it is recommended to upgrade to Airflow 2.11.1 or a later version, which addresses this issue. User...
DAG Author (who already has quite a lot of permissions) could manipulate database of Airflow 2 in the way to execute arbitrary code in the web-server context, which they should normally not be able to do, leading to potentially remote code execution in the context of web-server (server-side) as a result of a user viewing historical task information. [CVSS 8.4 HIGH]
When a DAG failed during parsing, Airflow’s error-reporting in the UI could include the full kwargs passed to the operators. If those kwargs contained sensitive values (such as secrets), they might be exposed in the UI tracebacks to authenticated users who had permission to view that DAG. [CVSS 6.5 MEDIUM]
Strimzi versions 0.47.0 through 0.50.0 improperly trust all certificates in a CA chain rather than only the intended signing authority, allowing Kafka Connect and MirrorMaker 2 operands to accept connections from brokers with certificates signed by intermediate CAs. An attacker could leverage this improper certificate validation to establish unauthorized connections to Kafka clusters using alternate CA-signed certificates from the trusted chain. This vulnerability requires high privileges to configure the CA chain and has no available patch at this time.
Improper Input Validation vulnerability in Apache Tomcat. Tomcat did not limit HTTP/0.9 requests to the GET method. [CVSS 3.7 LOW]
Input validation vulnerability in Apache Tomcat affecting versions 11.0.0-M1 through 11.0.14, 10.1.0-M1 through 10.1.34, and 9.0.0.M1 through 9.0.98. Critical severity issue in one of the most widely deployed Java application servers.
Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Avro Java SDK when generating specific records from untrusted Avro schemas. This issue affects Apache Avro Java SDK: all versions through 1.11.4 and version 1.12.0. [CVSS 7.3 HIGH]
Observable Timing Discrepancy vulnerability in Apache Shiro. This issue affects Apache Shiro: from 1.*, 2.* before 2.0.7. [CVSS 2.5 LOW]
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.
Apache::Session versions through 1.94 for Perl re-creates deleted sessions. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Stack overflow in ParquetSharp versions 18.1.0 through 23.0.0.0 allows remote unauthenticated attackers to cause denial of service by supplying a maliciously crafted Parquet file with a decimal column declaring an unreasonably large width, triggering unbounded stack allocation in the DecimalConverter.ReadDecimal method. This impacts network services that parse untrusted Parquet files. The vulnerability has been patched in version 23.0.0.1.
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.
Cross-site scripting (XSS) vulnerability in Apache Wicket allows unauthenticated remote attackers to inject malicious JavaScript through crafted strings that break out of JavaScript sequence contexts. Affected versions include Wicket 8.0.0-8.17.0, 9.0.0-9.22.0, and 10.0.0-10.8.0. User interaction (e.g., clicking a malicious link) is required for exploitation. EPSS score of 0.03% (8th percentile) indicates low empirical exploitation probability despite network-accessible attack vector.
Apache Thrift versions prior to 0.23.0 are vulnerable to a denial-of-service condition with unspecified attack mechanisms related to CWE-789 (uncontrolled memory allocation). The vulnerability affects multiple language implementations including Rust, Java, and Node.js, and can be triggered remotely without authentication or user interaction, though the technical mechanism remains partially obscured in available disclosures. With EPSS score of 0.02% (percentile 5%), active exploitation appears unlikely despite the low CVSS complexity score.
Quarkus OpenAPI Generator versions before 2.16.0-lts and 2.16.0 (fixed in 2.17.0) send authentication credentials to unintended API endpoints due to overly broad path-parameter regex matching. The generated authentication filter treats OpenAPI path-template placeholders like {param} as .* patterns, allowing a single parameter to consume forward slashes and match multiple distinct operations. This causes bearer tokens, OAuth tokens, API keys, and basic credentials configured for one protected operation to be leaked to different, unprotected operations on the same service when a client invokes them through normal generated-code paths. No public exploit code has been identified, but the vulnerability is trivial to trigger and affects all authentication schemes relying on the shared path-matching logic.
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.
Out-of-bounds read in Apache Thrift C++ JSON deserialization allows remote attackers to leak sensitive information and trigger denial of service via malformed JSON payloads. Affects Apache Thrift versions prior to 0.23.0. The vulnerability has low exploitation probability (EPSS 0.02%) and is not currently listed in CISA KEV, suggesting limited real-world weaponization despite network-accessible attack vector.
Stack overflow in Apache Thrift c_glib dispatch mechanism allows remote attackers to trigger denial of service via crafted network requests. The vulnerability affects Apache Thrift versions prior to 0.23.0 and requires no authentication or user interaction, resulting in application crashes or service unavailability. Patch is available from the vendor.
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.
Apache Airflow versions prior to 3.2.1 allow authenticated users with read access to at least one directed acyclic graph (DAG) to enumerate and discover the names and existence of all other DAGs and assets in the deployment, regardless of their assigned permissions. This information disclosure vulnerability enables privilege escalation reconnaissance by revealing the complete asset topology to users with limited scope authorization. The vulnerability requires valid user credentials but no elevated privileges, and has no known public exploit code at time of analysis.
Apache Airflow versions prior to 3.2.1 fail to enforce per-DAG access control on the /ui/dags endpoint, allowing authenticated users with read access to at least one DAG to retrieve Human-in-the-Loop prompts and full TaskInstance details for DAGs outside their authorized scope. This information disclosure bypasses the intended per-DAG RBAC boundary, exposing operator parameters and task context data to all authenticated users regardless of their assigned DAG permissions.
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.
CRLF injection in HTTP Headers WordPress plugin up to version 1.19.2 allows authenticated administrators to inject arbitrary Apache directives into .htaccess files via unsanitized custom header fields, causing configuration parse errors and potential site-wide denial of service. Attack requires Administrator-level WordPress access and no user interaction. CVSS 5.5 reflects high availability impact (A:H) balanced against high privilege requirements (PR:H).
Roxy-WI versions prior to 8.2.6.4 allow authenticated attackers to read arbitrary files via path traversal in the POST /config/<service>/show API endpoint. The configver parameter is directly concatenated into a file path without proper validation, permitting directory escape sequences (../) to bypass the existing path guard. An authenticated user can exploit this to access sensitive configuration files and other data readable by the web application process.
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.
Apache Airflow 3.0.0 through 3.1.x fails to invalidate JWT tokens at logout, allowing intercepted tokens to remain valid for unauthorized API access. This session management weakness enables replay attacks against the workflow orchestration platform's REST API. No active exploitation confirmed (EPSS 3rd percentile), but SSVC rates as automatable with partial technical impact. Vendor-released patch: Apache Airflow 3.2.0.
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.
Authenticated denial of service via CQL in Apache Cassandra 4.0 through 5.0 allows authenticated users to elevate query latencies by repeatedly changing passwords, disrupting service availability for legitimate users. The vulnerability affects Cassandra 4.0.0-4.0.19, 4.1.0-4.1.10, and 5.0.0-5.0.6. Vendor-released patches are available (4.0.20, 4.1.11, 5.0.7). With an EPSS score of 0.02% (5th percentile), real-world exploitation risk is minimal despite the moderate CVSS score of 6.5, reflecting the requirement for prior authentication and the low likelihood of widespread abuse.
Apache Cassandra 4.0 through 4.0.19 stores cleartext passwords and other sensitive command history in the ~/.cassandra/cqlsh_history file without redaction, allowing local authenticated users to extract credentials via direct file access. Vendor-released patch available in version 4.0.20; exploitation requires local file system access and existing user privileges but poses significant risk in multi-tenant or shared system environments.
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
VA MAX 8.3.4 contains a remote code execution vulnerability that allows authenticated attackers to execute arbitrary commands by injecting shell metacharacters into the mtu_eth0 parameter. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
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.
Apache Artemis before version 2.52.0 contains an authentication bypass vulnerability (CVE-2026-27446) that allows attackers to read all messages exchanged via the broker and inject new messages. KNIME Business Hub, which embeds Apache Artemis, is affected across all versions, though exploitation requires an authenticated user with workflow execution privileges who can register a federated mirror without authenticating to the underlying Artemis instance. While no public exploit code has been disclosed and CVSS scoring is unavailable, the vulnerability represents a significant insider threat with direct impact on message confidentiality and integrity.
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.
Mod_gnutls versions prior to 0.13.0 fail to validate the Extended Key Usage (EKU) extension during client certificate verification, allowing an attacker with a valid certificate issued for a different purpose to improperly authenticate for TLS client certificate-based access. Only Apache HTTPD servers configured to use client certificate authentication (via GnuTLSClientVerify settings other than 'ignore') are affected. The vulnerability enables unauthorized information disclosure through certificate misuse, with a CVSS score of 6.8 reflecting high confidentiality impact but requiring non-trivial attack complexity.
FileRise, a self-hosted web file manager and WebDAV server, contains an unrestricted file upload vulnerability in its WebDAV endpoint that bypasses filename validation controls present in the regular upload path, allowing authenticated attackers to upload executable file types such as .phtml, .php5, and .htaccess. In non-default Apache configurations lacking LocationMatch protection, this enables remote code execution on the underlying web server. The vulnerability affects FileRise versions prior to 3.8.0 and has been patched; no public exploit code or active KEV listing is currently confirmed, but the presence of a GitHub security advisory indicates vendor acknowledgment of the threat.
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.
Critical hardcoded credentials vulnerability in ZKTeco ZKBioSecurity 3.0's bundled Apache Tomcat server that allows unauthenticated remote attackers to upload malicious WAR files and execute arbitrary code with SYSTEM privileges. Multiple public exploits are available (Exploit-DB, Packet Storm), making this a high-risk vulnerability for organizations using this biometric security management software.
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.
A security flaw has been discovered in perfree go-fastdfs-web up to 1.3.7. This affects the function rememberMeManager of the file src/main/java/com/perfree/config/ShiroConfig.java of the component Apache Shiro RememberMe. Performing a manipulation results in use of hard-coded cryptographic key . The attack can be initiated remotely. The complexity of an attack is rather high. The exploitability is reported as difficult. The exploit has been released to the public and may be used for attacks...
Apache PDFBox versions 2.0.24-2.0.35 and 3.0.0-3.0.6 contain a path traversal vulnerability in the ExtractEmbeddedFiles example that allows attackers to write files outside the intended extraction directory by manipulating embedded file names. Organizations that have integrated this example code into production systems are at risk of unauthorized file writes on the host system. No patch is currently available, requiring developers to manually implement path validation to ensure extracted files remain within the designated directory.
AWS Airflow Providers with Auth Manager fail to validate SAML response origins against the actual instance URL, allowing attackers with valid credentials from one instance to authenticate to other instances with potentially different access controls. This cross-instance authentication bypass requires low privileges and network access but does not directly compromise confidentiality or integrity. Users should upgrade to version 9.22.0 or later to remediate this vulnerability.
Airflow Providers Http is affected by improper control of dynamically-managed code resources (CVSS 8.8).
Insecure session ID generation in Apache::Session::Generate::MD5 through 1.94 for Perl.
Apache ActiveMQ does not properly validate the remaining length field which may lead to an overflow during the decoding of malformed packets. [CVSS 5.4 MEDIUM]
Hostname verification bypass issue in Apache Ranger NiFiRegistryClient/NiFiClient is reported in Apache Ranger versions <= 2.7.0. Users are recommended to upgrade to version 2.8.0, which fixes this issue. [CVSS 5.3 MEDIUM]
RCE in Apache Ranger <= 2.7.0 via NashornScriptEngineCreator. EPSS 0.42%.
Apache\ versions up to \ contains a vulnerability that allows attackers to gain access to systems (CVSS 8.2).
Authenticated users in Apache Superset versions before 6.0.0 can execute write operations against PostgreSQL databases configured as read-only by crafting specially formatted SQL statements that evade validation checks. This allows an attacker with SQLLab access to perform unauthorized data modifications despite read-only protections being in place. No patch is currently available for affected versions.
Authenticated users in Apache Superset versions before 6.0.0 can access sensitive user information including password hashes and email addresses through the Tag endpoint API, which improperly exposes user objects without proper field filtering. An attacker with low-privilege credentials (such as Gamma role) can exploit this to retrieve authentication data that should remain hidden. The vulnerability only affects instances with the TAGGING_SYSTEM enabled, which is disabled by default.
Apache Superset before version 6.0.0 contains an authorization bypass in dataset management that allows authenticated users with write access to datasets to circumvent data access controls and query unauthorized information. An attacker can exploit this by modifying the SQL query of existing datasets to access restricted data that their role should not permit. No patch is currently available, leaving affected deployments vulnerable until upgrading to version 6.0.0.
Apache Superset before version 6.0.0 contains a SQL injection vulnerability in the sqlExpression and where parameters that allows authenticated users with read access to extract sensitive data through error-based techniques. An attacker with valid credentials could exploit this to bypass query restrictions and access unauthorized database information. A patch is available in version 6.0.0 and later.
Insufficient SQL function restrictions in Apache Superset before 4.1.2 allow authenticated users to execute sensitive database functions on ClickHouse engines that should have been blocked. An attacker with database access could leverage the incomplete DISALLOWED_SQL_FUNCTIONS list to bypass security controls and potentially extract or manipulate data. No patch is currently available for affected versions of Apache Superset, PostgreSQL, and related deployments.
Airflow versions before 2.11.1 have a vulnerability that allows authenticated users with audit log access to see sensitive values in audit logs which they should not see. When sensitive connection parameters were set via airflow CLI, values of those variables appeared in the audit log and were stored unencrypted in the Airflow database. While this risk is limited to users with audit log access, it is recommended to upgrade to Airflow 2.11.1 or a later version, which addresses this issue. User...
DAG Author (who already has quite a lot of permissions) could manipulate database of Airflow 2 in the way to execute arbitrary code in the web-server context, which they should normally not be able to do, leading to potentially remote code execution in the context of web-server (server-side) as a result of a user viewing historical task information. [CVSS 8.4 HIGH]
When a DAG failed during parsing, Airflow’s error-reporting in the UI could include the full kwargs passed to the operators. If those kwargs contained sensitive values (such as secrets), they might be exposed in the UI tracebacks to authenticated users who had permission to view that DAG. [CVSS 6.5 MEDIUM]
Strimzi versions 0.47.0 through 0.50.0 improperly trust all certificates in a CA chain rather than only the intended signing authority, allowing Kafka Connect and MirrorMaker 2 operands to accept connections from brokers with certificates signed by intermediate CAs. An attacker could leverage this improper certificate validation to establish unauthorized connections to Kafka clusters using alternate CA-signed certificates from the trusted chain. This vulnerability requires high privileges to configure the CA chain and has no available patch at this time.
Improper Input Validation vulnerability in Apache Tomcat. Tomcat did not limit HTTP/0.9 requests to the GET method. [CVSS 3.7 LOW]
Input validation vulnerability in Apache Tomcat affecting versions 11.0.0-M1 through 11.0.14, 10.1.0-M1 through 10.1.34, and 9.0.0.M1 through 9.0.98. Critical severity issue in one of the most widely deployed Java application servers.
Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Avro Java SDK when generating specific records from untrusted Avro schemas. This issue affects Apache Avro Java SDK: all versions through 1.11.4 and version 1.12.0. [CVSS 7.3 HIGH]
Observable Timing Discrepancy vulnerability in Apache Shiro. This issue affects Apache Shiro: from 1.*, 2.* before 2.0.7. [CVSS 2.5 LOW]
