A flaw was found in the SAML metadata import functionality of the keycloak-services component, which is the core engine for identity brokering in Red Hat Build of Keycloak. When importing identity provider metadata that lacks specific usage attributes for keys, the system incorrectly disables signature validation for SAML responses even if a signing certificate is provided. This issue allows an un…

Subrion CMS's admin grid sorting helper, _gridGetSorting() in includes/classes/ia.base.controller.admin.php, whitelists the `dir` (ASC/DESC) request parameter via in_array(), but falls back to the raw, attacker-supplied `sort` GET parameter whenever the requested key is not present in the per-controller $_gridSorting whitelist array: `$column = isset($this->_gridSorting[$params['sort']]) ? ... : $…

imagecli's `scale ` pipeline operation (Scale::apply() in src/image_ops.rs) computes output width/height as (dimension as f32 * ratio) as u32 with no upper-bound validation on the CLI-supplied ratio, which is parsed via nom::number::complete::float with no range check. A large ratio (e.g. 100000) causes an attempted allocation of hundreds of terabytes, aborting the process. Any application …

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.10.0 until 0.11.0, src/lib/components/chat/Messages/Markdown/KatexRenderer.svelte could store and render a chat message whose math block makes KaTeX fail with a stack overflow instead of a parse error. The catch branch fell back to inserting the original math source into the page as HTML through {@html} ra…

OpenCode Studio before 2.4.4 contains a missing authentication vulnerability that allows unauthenticated remote attackers to read arbitrary files within the temp and static/music directories by directly accessing the GET /api/tmp/:tmpFile and GET /api/music/:fileName endpoints. Attackers can retrieve intermediate audio, video artifacts, and subtitles belonging to other users' jobs, and additionall…

Emlog Pro through 2.6.23 contains a disabled TLS certificate validation vulnerability in include/service/ai.php that allows network-adjacent attackers to intercept outbound HTTPS requests to configured LLM providers by presenting arbitrary TLS certificates, as CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST are unconditionally disabled across sendStream(), sendImageRequest(), send(), and fetchSe…

Net::SAML2 versions before 0.86 for Perl allow SAML authentication bypass via XML signature wrapping because new_from_xml reads assertion identity with document-wide XPath instead of the signed subtree. new_from_xml reads the NameID, attribute values, SessionIndex, audience and other identity fields with document-wide XPath, such as //saml:Assertion/saml:AttributeStatement/saml:Attribute and //sa…

Net::SAML2 versions before 0.86 for Perl allow authentication bypass because _verify_encrypted_assertion accepts an EncryptedAssertion whose decrypted content carries no signature. _verify_encrypted_assertion decrypts the EncryptedAssertion and returns it as verified when it carries no signature, via "return $xml unless $xpath->exists('dsig:Signature', $assert);". The signature check and the trus…

Net::SAML2 versions before 0.86 for Perl allow SAML authentication bypass by verifying responses against the response-embedded certificate in verify_xml when no trust anchor is configured. verify_xml in Net::SAML2::Role::VerifyXML runs "return if !$anchors && !$cacert;" as soon as the XML::Sig check succeeds, and that check uses the X.509 certificate taken from the response's own dsig:KeyInfo/dsi…

better-auth versiones anteriores a 1.6.11 contiene defectos criptográficos en los plugins oidcProvider y mcp que permiten negociar el algoritmo 'none' y aceptan PKCE en texto plano en lugar de S256. Los atacantes pueden obtener tokens sin firma o interceptar códigos de autorización, comprometiendo sistemas de autenticación y autorización en infraestructuras cloud y on-premises que utilicen estas bibliotecas.

GitPython versiones anteriores a 3.1.50 no valida correctamente caracteres de salto de línea en el parámetro section de config_writer(), permitiendo a atacantes inyectar encabezados arbitrarios en .git/config. Los adversarios pueden manipular la sección [core] para dirigir hooksPath hacia directorios controlados, logrando ejecución de código remoto cuando se activan hooks de Git. Esta vulnerabilidad afecta principalmente a repositorios compartidos y entornos de integración continua en empresas de México y Latinoamérica.

Las versiones de @better-auth/sso anteriores a 1.6.21 contienen múltiples vulnerabilidades que permiten a atacantes eludir mecanismos de autenticación SSO y acceder como usuarios arbitrarios. Los vectores incluyen fallas en validación de dominios, cuentas huérfanas de proveedores, aserciones SAML sin vinculación y XSS reflejado en endpoints de cierre de sesión, exponiendo sistemas de autenticación centralizada en empresas de LATAM que utilizan este componente en plataformas cloud o híbridas.
