CVE-2026-34916Network attack vector

Authenticated PHP execution via unchecked logical operator

Published Jun 23, 2026 · Updated Jun 23, 2026

Code injection in Revive Adserver 6.0.6 and earlier allows remote authenticated users to execute PHP during banner delivery. The delivery-limitation save path accepts an arbitrary logical parameter and stores it in compiledlimitations without restricting it to the expected AND and OR operators. Low-privileged management access is sufficient; injected code later runs in the ad-serving process with the service's privileges.
