CVE-2026-77168

A cross-site request forgery vulnerability in tracker-invocation.php in Revive Adserver 6.0.8 and earlier allows an attacker to modify a tracker's name, description or advertiser assignment using an authenticated victim's permissions. A leftover state-changing handler accepts request parameters without verifying a CSRF token, although it is not used by the normal invocation-tag interface. Exploitation requires victim interaction and a request path that carries the victim's session credentials. The issue is fixed in Revive Adserver 6.0.9 by removing the unused tracker-modification handler.
