CVE-2026-126541

WWBN AVideo through 29.7.1 contains a missing authorization vulnerability in API::get_api_tags() in plugin/API/API.php that allows registered users to access restricted video data by querying the tags API. Attackers can obtain filenames, titles, and stored video_password values of unlisted, group-restricted, and password-protected videos.

WWBN AVideo 6.5 through 29.7.1 contains an email verification bypass vulnerability in User::verifyCode() in objects/user.php caused by PHP loose comparison of the recoverPass token. Registered users can reuse the installation-wide salt from their own verification link and craft a code with arbitrary users_id and recoverPass set to true to verify other accounts' emails.

WWBN AVideo through 29.7.1 contains an improper payment verification vulnerability in plugin/PayPalYPT/ipnV2.php that credits wallets from PayPal IPNs not bound to the site's merchant account. Unauthenticated attackers can forward genuine VERIFIED recurring-payment IPNs from their own PayPal account with a chosen users_id to add wallet balance each billing cycle.

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 6.5 through 29.7.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as any user via Hybridauth social login display names. Attackers can set their X, Facebook, Yahoo or LinkedIn display name to a victim's username and withhold email, causing login.json.php or oauth2.php to log them in as that account, including administrators, without a password.

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 contains a path traversal vulnerability in plugin/AI/receiveAsync.json.php that allows holders of any valid AI token to write arbitrary .vtt files by injecting traversal sequences into the unsanitized response[lang] parameter. Attackers can send a type=translation request with a crafted lang value to plant attacker-controlled content in the webroot or overwrite other users' subtitle files.

WWBN AVideo 29.0 through 29.4.0 contains a race condition vulnerability in plugin/PayPalYPT/ipn.php that allows attackers to bypass IPN replay protection due to a non-atomic deduplication check and insert. Attackers can concurrently replay a captured valid recurring-payment notification so both requests pass isRecurringPaymentIdUsed(), obtaining duplicate wallet credits and subscription renewals.
