What is CVE-2026-126541?

The WWBN AVideo Live plugin, up to version 29.7.1, exhibits a missing authorization flaw that allows authenticated streamers to access other users' stream keys. By exploiting this vulnerability, attackers can input arbitrary identifiers into the live transmission history, thereby gaining unauthorized access to sensitive data such as HLS URLs and stream keys. This enables malicious actors to impersonate victims, potentially publishing or restreaming private or pay-per-view livestreams without consent. Ensuring appropriate access controls and authorization checks are imperative to safeguard user data against such unauthorized disclosures.

Affected Version(s)
