cacti: Cacti is an open source performance and fault management framework
CVE-2026-40082 is fixed in cacti on 1 platform by DEBIAN-CVE-2026-40082 (version 1.2.31+ds1-1), released July 14, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have missing session_regenerate_id() after login, leading to Session Fixation. session_regenerate_id() is NOT called after successful login. The login flow at auth_login.php:203-207 directly sets $_SESSION[SESS_USER_ID] without rotating the session ID. The session cookie configuration is otherwise good (httponly=true, samesite=Strict, secure=true for HTTPS at include/global.php:513-537), but these do not prevent session fixation via same-site vectors. This issue has been fixed in version 1.2.31.
