CVE-2026-34915: Revive Adserver

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

A missing sanitisation of user input in the zone-include.php script of Revive Adserver 6.0.6 and earlier could allow a low‑privileged user to exploit the clientid parameter to perform blind SQL injection attacks. Input sanitisation has been improved to ensure that all parameters processed by the script are properly validated.

Affected products
