CVE-2026-50739

Obejście walidacji właściciela w Revive Adserver pozwala na nieautoryzowane łączenie trackerów z kampaniami.

A bypass for CVE‑2026‑34913 exists with proper ownership validation that had not been applied to the reverse operation of linking campaigns and trackers through the `tracker-campaigns.php` script in Revive Adserver 6.0.7 and earlier. As a result, a low‑privileged user could link their trackers to campaigns owned by other managers on the same instance, leading to inconsistent ownership relationships.
