Official Description

WWBN AVideo is an open source video platform. In versions up to and including 26.0, AVideo's `_session_start()` function accepts arbitrary session IDs via the `PHPSESSID` GET parameter and sets them as the active PHP session. A session regeneration bypass exists for specific blacklisted endpoints when the request originates from the same domain. Combined with the explicitly disabled session regeneration in `User::login()`, this allows a classic session fixation attack where an attacker can fix a victim's session ID before authentication and then hijack the authenticated session. Commit 5647a94d79bf69a972a86653fe02144079948785 contains a patch.

Technical Analysis

CVE-2026-33492 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 7.3.
