What is CVE-2026-108562?

A stored cross-site scripting vulnerability exists in the maintenance-appendcode-check.php component of Revive Adserver up to version 6.0.8. This flaw allows an authenticated manager to insert a malicious tracker name, which is subsequently displayed in the maintenance results without proper HTML encoding. When an administrator views the maintenance page, the malicious JavaScript can execute in the admin's browser, potentially compromising sensitive information or the security of the application. The vulnerability has been addressed in Revive Adserver version 6.0.9, which adds HTML encoding to tracker names in the maintenance results.
