Technical description

AVideo through 29.0 contains an authorization bypass vulnerability in the Meet plugin's uploadRecordedVideo.json.php endpoint that derives the target users_id from the uploaded filename without verification. An attacker with knowledge of the Meet shared secret can craft a malicious file upload with a filename containing an arbitrary users_id to invoke passwordless User->login() and establish an authenticated session as any user including admin. Attackers can obtain the Meet shared secret through path-traversal vulnerabilities or timing attacks against checkToken.json.php, then POST a crafted file to uploadRecordedVideo.json.php with a filename like '1-anything.mp4' to hijack admin sessions and gain full account takeover.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
