CVE-2025-62781

PILOS (Platform for Interactive Live-Online Seminars) is a frontend for BigBlueButton. Prior to 4.8.0, users with a local account can change their password while logged in. When doing so, all other active sessions are terminated, except for the currently active one. However, the current session’s token remains valid and is not refreshed. If an attacker has previously obtained this session token through another vulnerability, changing the password will not invalidate their access. As a result, the attacker can continue to act as the user even after the password has been changed. This vulnerability is fixed in 4.8.0.

Summary		(es) PILOS (Platform for Interactive Live-Online Seminars) es un frontend para BigBlueButton. Antes de la versión 4.8.0, los usuarios con una cuenta local pueden cambiar su contraseña mientras están conectados. Al hacerlo, todas las demás sesiones activas se terminan, excepto la que está activa actualmente. Sin embargo, el token de la sesión actual sigue siendo válido y no se actualiza. Si un atacante ha obtenido previamente este token de sesión a través de otra vulnerabilidad, cambiar la contraseña no invalidará su acceso. Como resultado, el atacante puede seguir actuando como el usuario incluso después de que la contraseña haya sido cambiada. Esta vulnerabilidad se corrige en la versión 4.8.0.
