RCE in Revive Adserver
CVE-2026-44959
A missing validation of user input exists when saving delivery limitations in Revive Adserver 6.0.6 and earlier. A low‑privileged user could add an unexpected component parameter and inject malicious PHP code into the compiledlimitations field, which would then be executed during banner delivery. Input sanitisation has been improved to ensure that unexpected parameters are filtered out.
