SCA: security update for wwbn/avideo (GHSA-95jh-7r58-xmxw)

medium Tenable Self-Hosted Container Security Plugin ID 443798

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - WWBN AVideo is an open source video platform. In versions prior to 29.0, the Authorize.Net webhook handler
 at plugin/AuthorizeNet/webhook.php contains a signature verification bypass that allows an attacker to
 forge webhook requests with arbitrary payment amounts and target user IDs. By supplying a valid
 transaction ID from a small legitimate purchase, the attacker bypasses signature validation and credits
 arbitrary wallet balances to any user account via attacker-controlled payload fields. Three flaws combine
 into an exploit chain: signature bypass via OR logic (webhook.php:33), payload values override API-fetched
 values (AuthorizeNet.php:169-171, webhook.php:44-48) and a missing approval check (webhook.php:61-75). By
 forging payment metadata, an attacker can credit arbitrary amounts to any user's wallet without a
 corresponding payment and include a plans_id to activate premium subscriptions (webhook.php:86-134),
 enabling free access to all paid and premium content and causing direct revenue loss to the platform
 owner. This issue has been fixed in version 29.0. (CVE-2026-33731)

Solution

Update the wwbn/avideo library and its related packages to version 29.0 or later.
