Low risk7th percentile - higher than 7% of all known CVEs
Summary
Prior to 8.1.0, AVideo's view/queue.php uses pathinfo on the caller-controlled fileURI and stores its filename through setTitle in encoder_queue.title without neutralization. fileURI is not covered by the objects/security.php filter lists, and the Login::canUpload() capability can be self-granted, allowing an attacker to store an HTML title whose event handler runs in a privileged viewer's browser (an administrator or an operator on the attacker's streamer).
Risk Assessment
An authenticated attacker can execute arbitrary JavaScript in a privileged user's context, read session data and rendered streamer credentials, and act with the viewer's privileges. The script can execute again for each qualifying viewer until the row is removed.
Recommendation
Upgrade AVideo to version 8.1.0 or later. Restrict self-granting of the canUpload capability and verify that queue titles are encoded before being inserted into HTML.
Other vulnerabilities in AVideo
See all- CVE-2026-89255High
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the LoginControl plugin that fails to HTML-encode PGP public keys echoed into a textarea element. An authenticated attacker can inject malicious JavaScript by submitting a crafted public key, which executes in an administrator's session when viewing the user's profile tab.
- CVE-2026-89253High
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the user 'donationLink' profile field. User::setDonationLink() stores the value and save() validates it only with filter_var(..., FILTER_VALIDATE_URL), which accepts strings such as http://evil.example/"onmouseover=alert(document.domain)//, while getDonationLink() applies only strip_tags() and does not encode double quotes. An authenticated user who updates their own profile can break out of the href attribute and inject an event handler that executes JavaScript in the browser of any visitor, including an administrator.
- CVE-2026-89250High
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains an unauthenticated file read vulnerability in the getRecordedFile.php endpoint that streams recorded FLV files from the temporary directory. Attackers can request the endpoint with a known or guessed stream key to download recorded live video files without authentication or authorization checks.
- CVE-2026-89248Medium
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 is missing an authentication/authorization check in plugin/WebRTC/status.json.php. When the WebRTC plugin is present, any unauthenticated remote user can request the endpoint and receive JSON containing the absolute filesystem path of the WebRTC2RTMP helper binary, the configured WebRTC port, file_exists/is_executable status, log contents, and port reachability information.
- CVE-2026-89245Medium
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in playlistRemove.php that allows attackers to delete playlists by skipping CSRF protection checks. Attackers can craft a malicious form that submits a POST request to playlistRemove.php.
- CVE-2026-89240Medium
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in plugin/Live/confirmLivePassword.php. The unauthenticated GET parameter u is interpolated directly into an img src attribute without URL- or HTML-encoding, allowing injection of an additional tag with an onerror handler.
- CVE-2026-89148Medium
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains an open redirect in objects/playlistSort.php. Because the endpoint is not a *.json.php script, AVideo's automatic CSRF guard (autoCSRFGuard()/forbidIfIsUntrustedRequest()) does not run, and when the request includes the sort parameter the script issues a Location header set to the unvalidated $_SERVER['HTTP_REFERER'] value without calling isSafeRedirectURL(). A remote unauthenticated attacker can therefore induce a logged-in user who can manage the targeted playlist to submit a cross-origin POST with a crafted Referer, causing the victim's playlist to be reordered and the victim's browser to be redirected from a trusted AVideo URL to an attacker-controlled site for phishing. No patched version is available.
- CVE-2026-88874High
AVideo through revision c3edcc274c389816d434acadac07ee78eaf330c1 does not enforce the Live stream password check on the stats endpoint or on the HLS origin. Live::_getStats() returns a password-protected transmission's RTMP stream key, isPasswordProtected flag, and HLS URL to unauthenticated callers, and the shipped NGINX configuration serves the .m3u8 playlist, AES-128 key, and transport-stream segments without authentication.
- CVE-2026-88873High
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in view/logArchive.json.php. Unauthenticated attackers can archive application logs via GET requests without CSRF token validation, copying sensitive logs to a publicly accessible zip file and truncating the live log.
- CVE-2026-88872High
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in the setPassword.json.php endpoint. Unauthenticated attackers can modify any user's channel password by sending a GET request without CSRF token validation.
Original NVD description (English source)
AVideo is a video-sharing Platform. Prior to 8.1.0, `view/queue.php` uses `pathinfo` on the caller-controlled `fileURI` and stores its filename through `setTitle` in `encoder_queue.title` without neutralization. `fileURI` is not in the `objects/security.php` filter lists, and the `Login::canUpload()` capability needed to submit a queue entry can be self-granted using an attacker-controlled login site without legitimate encoder credentials. `view/index.php` loads `queue.json` from `view/queue.json.php` into the `#grid` jQuery Bootgrid table; its title formatter concatenates `row.title` into raw cell HTML. An attacker can therefore store an HTML title whose event handler runs in a privileged viewer's browser. `Encoder::getAll` limits nonadministrators to their own streamer's rows, so the victim must be an administrator who sees all rows or an operator on the attacker's streamer. A second `.html()` sink in the progress panel uses the same title but additionally depends on a helper script loaded from the streamer; the Bootgrid sink is reachable from encoder code alone. The script can read session-visible data and rendered streamer credentials, act with the viewer's privileges, and execute again for each qualifying viewer until the row is removed. This issue is fixed in version 8.1.0.
