What is CVE-2026-45580?

WWBN AVideo, an open source video platform, contains a vulnerability that allows for stored cross-site scripting (XSS). In versions up to 29.0, the Live plugin improperly exposes live transmission stream keys in an HTML class attribute without adequate escaping measures. This flaw allows users with streaming capabilities to inject malicious JavaScript, which can then be executed by any visitor to the live stream page, whether they are logged in or not. This presents a significant risk as attackers could leverage this to execute unauthorized actions or extract sensitive information from users.
