CVE-2026-33719Public exploitNetwork attack vector

Unauthenticated CDN takeover via empty-key bypass

Published Mar 23, 2026 · Updated Mar 23, 2026

Missing authentication in the AVideo CDN plugin 26.0 and earlier allows remote attackers to overwrite persistent CDN configuration. The status.json.php and disable.json.php endpoints skip key comparison when the stored key is empty, then status.json.php assigns attacker-controlled par properties to the plugin object and saves it. Exploitation requires the CDN plugin to be enabled with its default unconfigured key and grants control of CDN URLs, storage credentials, the key itself, or plugin availability.
