Internal data disclosure via unvalidated image URLs
Published Sep 3, 2026 · Updated Sep 3, 2026
SSRF in WWBN AVideo through commit c91b5975d allows remote authenticated users to read internal resources through image URLs. The set_api_userImages endpoint passes profileImg and backgroundImg directly to url_get_contents, whose initial file_get_contents request omits isSSRFSafeURL, then writes the response beneath the public web root. A valid API secret is required; exposed cloud metadata or internal-service responses can then be retrieved from public image paths.
