Vulnerabilidad crítica de omisión de autenticación en openssl_encrypt anteriores a v1.4.0

openssl_encrypt versiones previas a 1.4.0 contiene una vulnerabilidad de omisión de autenticación (CVSS 9.8) en pqc.py donde fallos en desencriptación AES-GCM activan una caída no autenticada a modo AES-CTR. Atacantes pueden modificar texto cifrado en tránsito para eludir verificación de integridad y ejecutar ataques de inversión de bits sin detección, comprometiendo confidencialidad e integridad de datos en sistemas financieros, gubernamentales y corporativos de LATAM.

Vulnerabilidad crítica en openssl_encrypt anteriores a 1.4.0 permite filtración de secretos

openssl_encrypt en versiones anteriores a 1.4.0 contiene una vulnerabilidad (CVSS 9.8) en la función PublicKeyBundle.from_dict() que procesa datos no verificados sin validar firmas criptográficas. Un atacante puede manipular bundles de claves públicas para cifrar datos con claves controladas por el atacante, exponiendo información sensible en bases de datos, sistemas de pago y plataformas cloud comúnmente utilizadas en LATAM.

Vulnerabilidad crítica CVE-2026-5430 en autenticación JWT permite acceso no autorizado

Múltiples fabricantes han reportado una vulnerabilidad crítica (CVSS 10.0) en mecanismos de autenticación JWT que aceptan tokens firmados con algoritmos no configurados explícitamente. Atacantes pueden falsificar tokens JWT con algoritmos alternativos que son validados incorrectamente, permitiendo acceso no autorizado a sistemas, bases de datos y controles administrativos. Este riesgo es especialmente grave en infraestructuras cloud, plataformas de API y soluciones de identidad ampliamente usadas en LATAM.

XML::Sig versions before 0.71 for Perl allow signature wrapping via duplicate ID. _get_signed_xml() in lib/XML/Sig.pm, called from verify(), resolves the SignedInfo Reference/@URI to a node with the XPath expression "//*[@ID='$id']" and returns the first node of the resulting node set.
