CVE-2026-41061

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in UserGroups::setGroup_name() that fails to sanitize group_name input. Administrators with canAdminUserGroups permission can inject malicious HTML and JavaScript that executes in the browser when other administrators access the user manager interface.

WWBN AVideo contains a broken access control vulnerability in videoViewsInfo endpoints that returns complete user records including password hashes, recovery tokens, and live session identifiers to unauthenticated callers when a hash parameter is provided. Attackers can use the disclosed session identifier to hijack viewer sessions, including administrator accounts, and obtain sensitive personal data for all video viewers.

WWBN AVideo contains a path traversal vulnerability in notify.ffmpeg.json.php that allows unauthenticated attackers to write files to arbitrary locations by supplying a caller-chosen path in the avideoRelativePath parameter. Attackers can replay any previously issued ciphertext as a notifyCode token, which is decrypted but never validated, to bypass authentication and write files to the application root and subdirectories.

WWBN AVideo contains an authentication failure vulnerability where the video_id_hash credential is a non-expiring, non-revocable bearer token that grants full administrator session access to the video owner's account. Attackers who obtain a video_id_hash can replay it indefinitely to authenticate as the video owner with full privileges, and the credential remains valid even after the owner changes their password.

WWBN AVideo before 29.5.0 contains a local file inclusion vulnerability that allows unauthenticated attackers to include PHP files outside the locale directory via a crafted Accept-Language header. Attackers can use overlapping traversal sequences like ....// to bypass single-pass removal in setLanguage(), executing existing server-side PHP files in the application context.

WWBN AVideo 26.0 through 29.3.0 contains a stored cross-site scripting vulnerability that allows authenticated commenters to inject JavaScript because markDownToHTML() preserves event-handler attributes in leading HTML blocks. Attackers can post a comment starting with an img tag carrying an onerror handler, which bypasses the inline sanitizer and executes in viewers' browsers under the application origin.

WWBN AVideo before 29.4.0 contains a blind server-side request forgery vulnerability in getHeaderContentTypeFromURL() because get_headers() follows redirects without re-validating targets with isSSRFSafeURL(). Authenticated uploaders can store a videoLink pointing to a redirector, causing internal GET requests when visitors view the video, enabling internal port scanning.

WWBN AVideo before 24.0 contains a cross-site request forgery vulnerability in legacy endpoints like playlistStatus.php that bypass the .json.php-only autoCSRFGuard() check. Attackers can lure logged-in users to a page with an auto-submitting form to make private playlists public, remove playlist videos, or forge video suggestions.

WWBN AVideo through 29.2.0 contains a stored cross-site scripting vulnerability that allows users with upload permission to inject script by setting a malicious video trailer1 URL. The value is rendered unescaped in YouPHPFlix2 templates and channel playlists, letting attackers break out of onclick strings or iframe src attributes to execute JavaScript in victims' browsers.

WWBN AVideo 12.4 through 29.2.0 contains a stored cross-site scripting vulnerability that allows authenticated uploaders to inject HTML by submitting doubly-encoded entities in video titles. Because safeString() strips tags before decoding entities and runs twice via setTitle() and save(), attackers can store markup that executes in trending, gallery, embed, and playlist pages.
