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 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…

Vulnerabilidad alta en better-auth anterior a v1.6.11 permite aceptar tokens sin firma

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.

Vulnerabilidad alta en GitPython anterior a 3.1.50 permite inyección de código remoto

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.

Vulnerabilidades altas de bypass de autenticación en @better-auth/sso anteriores a v1.6.21

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.

Thumbor is an open-source photo thumbnail service by globo.com. Prior to 7.8.0, Thumbor's filters:proportion() filter does not enforce an upper bound on and runs in the post-transform phase. An attacker can trigger extremely large resizes (CPU/memory exhaustion) and cause denial of service. This issue is fixed in 7.8.0.

Stored cross-site scripting in the participant URL handling in AWS Ops Wheel before PR #168 might allow an authenticated remote user to steal session tokens and escalate to full administrative control of the deployed instance via a crafted participant_url value containing a dangerous URI scheme. To remediate this issue, users should redeploy from the latest version of aws-ops-wheel.

@phun-ky/defaults-deep is a library like lodash defaultsDeep with array preservation and no lodash dependency. Prior to 2.0.5, defaultsDeep() recursively merges user-supplied objects without filtering proto, constructor, and prototype, allowing properties to be written to Object.prototype.

Prior to versions 4.1.136.Final and 4.2.16.Final, the OcspServerCertificateValidator flags an out-of-date OCSP response but does not stop processing it, so an expired GOOD response is still reported as VALID, letting an on-path attacker replay a stale GOOD response to bypass revocation of a since-revoked certificate.
