CVE-2026-84476

WWBN AVideo contains a broken access control vulnerability in the unauthenticated feed/index.php endpoint that disables per-video visibility checks when a program_id parameter is supplied. Attackers can enumerate playlist identifiers and retrieve unlisted and group-restricted videos by requesting the RSS feed with any visible playlist id, including empty playlists that return the entire site's hidden video catalogue.

WWBN AVideo fails to properly validate access controls on the public channel page, allowing unauthenticated visitors to view unlisted and group-restricted videos through hardcoded visibility flags and an undefined property. Attackers can access the channel endpoint to retrieve sensitive video content that should be hidden, including full URLs to unlisted videos and thumbnails of member-only content, regardless of the operator's hidePrivateVideos setting.

WWBN AVideo contains a SQL injection vulnerability in the sort column parameter of the get.json.php endpoint with APIName=channels that allows unauthenticated attackers to order results by arbitrary database columns including users.password and users.recoverPass. Attackers can exploit this ordering oracle to infer password hash values and recovery tokens, and trigger SQL errors that disclose the full query statement and database schema.

WWBN AVideo is an open source video platform that, in versions up to 29.0, allows unauthenticated users to read APISecret from objects/plugins.json.php. This enables them to call protected API endpoints, such as users_list, without logging in.

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 through commit 9c39d8c8 contains a cross-site request forgery vulnerability in the get_domain() and isSameDomain() functions that fail to properly validate referer origins. Attackers can forge requests from sibling subdomains or unparseable long-gTLD origins to perform administrative ObjectYPT writes including live server configuration changes.

WWBN AVideo contains a path traversal vulnerability in the API get_api_login_code endpoint that allows unauthenticated attackers to delete arbitrary .log files by supplying directory traversal sequences in the code parameter. Attackers can exploit this to destroy audit logs and probe for file existence on the server, with the vulnerability enabling both file deletion and information disclosure about the filesystem.

WWBN AVideo contains a cross-site request forgery vulnerability in sendEmail.json.php that allows authenticated administrators to send mail from the site's contact address by bypassing origin checks and captcha validation. Attackers can craft a malicious web page that, when visited by an authenticated admin, sends emails with attacker-controlled subject and body to arbitrary recipients, passing SPF/DKIM/DMARC validation for phishing and brand impersonation attacks.

WWBN AVideo contains an unauthenticated reflected cross-site scripting vulnerability in the url2Embed.json.php endpoint that allows attackers to inject malicious scripts by supplying URLs with HTML metacharacters. Attackers can mint an encrypted evideo payload containing unescaped markup, then deliver it as a legitimate-looking link on the site's own domain to execute JavaScript in victims' sessions and steal cookies or CSRF tokens.

WWBN AVideo (up to e01e41ecc and earlier) contains a brute-force rate limiting bypass in enforceRateLimit(), which protects login.json.php and 13 other endpoints. The attempt counter is stored via a cache layer that silently discards writes for clients identified as bots by isBot(). Since isBot() treats a missing User-Agent header as a bot, an attacker can submit unlimited login attempts, enabling unrestricted password-guessing attacks.
