CVE-2025-30189

When cache is enabled, some passdb/userdb drivers incorrectly cache all users with same cache key, causing wrong cached information to be used for these users. After cached login, all subsequent logins are for same user. Install fixed version or disable caching either globally or for the impacted passdb/userdb drivers. No publicly available exploits are known.

Summary		(es) Cuando la caché está habilitada, algunos controladores passdb/userdb almacenan en caché incorrectamente a todos los usuarios con la misma clave de caché, lo que provoca que se utilice información en caché incorrecta para estos usuarios. Después de un inicio de sesión en caché, todos los inicios de sesión posteriores son para el mismo usuario. Instale la versión corregida o deshabilite el almacenamiento en caché, ya sea globalmente o para los controladores passdb/userdb afectados. No se conocen exploits disponibles públicamente.
