What is CVE-2026-90536?

The AVideo platform by WWBN contains an improper access control vulnerability in its adsInfo API endpoint. This vulnerability allows unauthenticated attackers to access sensitive information, including password-protected video owner identifiers, merely by supplying a videos_id parameter.
