Detailsinfo A vulnerability, which was classified as problematic, has been found in WWBN AVideo up to 25.x. Affected by this issue is the function uploadVideoToLinkedIn of the component SocialMediaPublisher Plugin. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes: 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. The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-33319 since 03/18/2026. The exploitation is known to be difficult. The attack may be launched remotely. The exploitation requires an enhanced level of successful authentication. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1202. Upgrading to version 26.0 eliminates this vulnerability.
