CVE-2026-34916 is a high-severity remote code execution 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 in the database. That injected PHP is later executed during banner delivery, turning the issue into server-side code execution. The vendor states that the root cause is insufficient validation/sanitization of the affected parameter and that the fix improves input sanitisation to ensure the parameter is properly validated.
