CVE-2026-34912
Revive Adserver Missing Access Control Zone Linking Vulnerability
Description

A missing access control check when linking banners or campaigns to a zone through the zone-include.php script of Revive Adserver 6.0.6 and earlier, or via its API allows a low‑privileged user could link their zones to banners or campaigns owned by other managers on the same instance, resulting in inconsistent ownership relationships. Ownership validation has been added to ensure that banners and campaigns can only be linked to zones managed by the same account.
