What is CVE-2026-39367?

WWBN AVideo's EPG feature vulnerabilities arise from improper handling of user-controlled XML data. In affected versions (26.0 and prior), program titles are rendered directly into HTML without adequate sanitization or escaping. This flaw enables users with upload permissions to set a video’s epg_link to host malicious XML files. If a such a link is accessed, JavaScript embedded within elements executes in the browsers of unauthenticated visitors to the public EPG page. This exploit could lead to session hijacking and unauthorized account access, compromising user security dramatically.

Affected Version(s)

AVideo <= 26.0
