CVE-2026-33319 Details
Description
WWBN AVideo is an open source video platform. Prior to version 26.0, the `uploadVideoToLinkedIn()` method in the SocialMediaPublisher plugin constructs a shell command by directly interpolating an upload URL received from LinkedIn's API response, without sanitization via `escapeshellarg()`. If an attacker can influence the LinkedIn API response (via MITM, compromised OAuth token, or API compromise), they can inject arbitrary OS commands that execute as the web server user. Version 26.0 contains a fix for the issue.
A command injection vulnerability has been identified in the SocialMediaPublisher plugin of WWBN AVideo, prior to version 26.0. The issue arises in the 'uploadVideoToLinkedIn()' method, which constructs a shell command by directly inserting an upload URL from LinkedIn's API response without proper sanitization. This flaw allows an attacker, under certain conditions, to inject arbitrary operating system commands that execute as the web server user.
Users are advised to update to version 26.0 or later, where this vulnerability has been fixed. For those unable to update, the 'uploadVideoToLinkedIn()' method can be modified to sanitize the upload URL with 'escapeshellarg()' before executing the command. Alternatively, the 'exec()' call can be replaced with PHP's native cURL functions, which are already used in the same class.
