CVE-2026-88869 PUBLISHED

AVideo AD_Server Stored XSS via log.php label parameter

Assigner: VulnCheck
Reserved: 10.09.2026 Published: 10.09.2026 Updated: 10.09.2026

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the AD_Server plugin's log.php endpoint that fails to escape the label parameter before storage. An unauthenticated attacker can inject malicious HTML through the label parameter, which is later rendered unsanitized in the admin Ad Types report using jQuery .html(), allowing execution of arbitrary JavaScript in an administrator's browser session.
