Remote Code Execution in Revive Adserver delivery limitations
CVE-2026-34916 is a high-severity code injection vulnerability in Revive Adserver 6.0.6 and earlier. The flaw is caused by missing validation of user input when saving delivery limitations. A low-privileged user can abuse the logical parameter to inject malicious PHP code into the compiledlimitations field stored in the database. That injected PHP is later executed during banner delivery, resulting in server-side code execution within the context of the ad server. The issue stems from insufficient sanitization and validation of attacker-controlled input before it is persisted and subsequently interpreted as executable PHP.
