Remote code execution in Chamilo LMS versions prior to 1.11.38 allows authenticated users (including low-privilege students) to upload and execute arbitrary PHP code through the BigUpload endpoint. Attackers exploit insufficient file extension filtering by uploading .pht files containing malicious code, which Apache servers with default .pht handlers execute as PHP. The vulnerability enables authenticated attackers to achieve full server compromise through unrestricted arbitrary file write capabilities. No public exploit identified at time of analysis.
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 distribution channels (native, Conan, Homebrew), with vendor-released patch version 1.7.0 now available.
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.
Out-of-memory denial of service in Apache ActiveMQ allows unauthenticated remote attackers to exhaust broker memory via rapid TLSv1.3 KeyUpdate requests.

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.
Mod_gnutls, a TLS module for Apache HTTPD, contains a stack-based buffer overflow vulnerability in its client certificate verification code. Versions prior to 0.12.3 and 0.13.0 fail to validate the length of client-provided certificate chains before writing pointers to a fixed-size array, typically causing segmentation faults (denial of service) and theoretically enabling stack corruption. Only configurations explicitly requiring client certificate verification are affected; default configurations using 'GnuTLSClientVerify ignore' are not vulnerable.
The Jupiter X Core plugin for WordPress contains an unrestricted file upload vulnerability allowing authenticated users with Subscriber-level privileges or higher to upload dangerous file types including .phar, .svg, .dfxp, and .xhtml files. This stems from missing authorization checks in the import_popup_templates() function and insufficient file type validation in the upload_files() function. Successful exploitation leads to Remote Code Execution on Apache servers with mod_php configured to execute .phar files, or Stored Cross-Site Scripting attacks via malicious SVG and other file types on any server configuration.
An unauthenticated server-side request forgery (SSRF) vulnerability exists in AVideo's Live plugin test.php endpoint that allows remote attackers to force the server to send HTTP requests to arbitrary URLs. The vulnerability affects AVideo installations with the Live plugin enabled and can be exploited to probe internal network services, access cloud metadata endpoints, and retrieve content from internal HTTP resources. A proof-of-concept has been published demonstrating localhost service enumeration, and the vulnerability requires no authentication or user interaction to exploit.
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.

Remote code execution in FreeScout prior to version 1.8.206 allows authenticated users to upload `.htaccess` files that bypass file upload restrictions, enabling arbitrary code execution on Apache servers with `AllowOverride All` enabled. Public exploit code exists for this vulnerability. The attack requires valid user credentials but affects all FreeScout installations using the vulnerable PHP Laravel framework configuration.
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.
Deserialization of Untrusted Data vulnerability in Apache Camel LevelDB component. The Camel-LevelDB DefaultLevelDBSerializer class deserializes data read from the LevelDB aggregation repository using java.io.ObjectInputStream without applying any ObjectInputFilter or class-loading restrictions. [CVSS 8.8 HIGH]
Cross-realm token acceptance bypass in Apache Camel Keycloak security policy. The KeycloakSecurityPolicy fails to properly validate token issuers, accepting tokens from different Keycloak realms. PoC available.
Unauthenticated attackers can access sensitive files in GetSimple CMS when Apache's AllowOverride directive is disabled, bypassing .htaccess protections that restrict directory access. This configuration is common in hardened and shared hosting environments, exposing authorization credentials, API keys, and cryptographic salts in files like authorization.xml. Public exploit code exists for this vulnerability, and no patch is currently available.
Strimzi Kafka Operator versions 0.49.0-0.50.0 incorrectly trusts all intermediate CAs in a multistage certificate chain for mTLS authentication, allowing any user with a certificate signed by any CA in the chain to authenticate to Kafka listeners. This authentication bypass affects only deployments using custom Cluster or Clients CA with multi-level CA chains. No patch is currently available.
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.
