CVE-2026-43877 is a Cross-Site Request Forgery (CSRF) vulnerability in WWBN AVideo versions up to and including 29.0. The vulnerability exists in the legacy endpoint objects/userSavePhoto.php, which allows a logged-in user’s profile photo to be overwritten with arbitrary data via a base64 POST parameter. This endpoint lacks CSRF protections such as tokens, Origin/Referer checks, and MIME validation. Due to the platform's cookie policy (SameSite=None; Secure on HTTPS), an attacker can exploit this by tricking a logged-in user into visiting a malicious page, causing unauthorized profile photo changes and triggering a site-wide cache clear. No official patch or remediation level is confirmed in the provided data, though a commit referenced in the description suggests a fix was made. The CVSS score is 5.4, indicating medium severity.
