Netty (io.netty:netty-handler) versions from 4.2.0.Final through 4.2.16.Final and versions through 4.1.136.Final disable TLS hostname verification on the SslProvider.OPENSSL client path when a plain (non-extended) X509TrustManager is used and Unsafe-based trust-manager wrapping is unavailable (Java 25+). In this configuration the OpenSSL client does not perform hostname verification, allowing a ma…

Vulnerabilidad alta en openssl_encrypt: clave secreta hardcodeada compromete autenticación de API

Versiones de openssl_encrypt anteriores a 1.4.0 contienen una clave secreta predeterminada hardcodeada en la configuración del servidor de telemetría, usada para hash de claves API. Atacantes que conocen este valor pueden falsificar hashes de API para comprometer la autenticación del sistema de telemetría. Esto afecta directamente a infraestructuras en la nube y servidores locales que dependen de esta validación criptográfica.

Vulnerabilidad alta en openssl_encrypt: secretos JWT hardcodeados permiten falsificación de tokens

Versiones de openssl_encrypt anteriores a 1.4.0 contienen secretos de firma JWT hardcodeados en config.py que superan validaciones, permitiendo a atacantes con acceso al código fuente forjar tokens válidos para cualquier client_id y acceder sin autorización a APIs de keyserver y telemetría. Afecta especialmente a organizaciones en LATAM que utilizan esta librería en aplicaciones de autenticación y gestión de claves.
