Executive Summary

CVE-2026-82643 is an unauthenticated credential submission vulnerability in WWBN AVideo's plugin/Live/api/preauthorize.json.php endpoint. It allows attackers to submit credentials via GET requests without rate limiting, triggering unlimited two-factor authentication emails and enabling password guessing attacks.

Detection Guidance

Check for repeated GET requests to the endpoint /plugin/Live/api/preauthorize.json.php with credential parameters. Monitor for excessive 2FA email triggers or failed login attempts from the same IP. Use tools like Wireshark or tcpdump to inspect HTTP traffic for suspicious patterns targeting this path.

Impact Analysis

Attackers can perform brute-force attacks on user accounts, flood mailboxes with 2FA emails causing MFA fatigue, and potentially gain unauthorized access. The lack of rate limiting allows sustained credential submission attempts.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's security rules for protected health information. It undermines access controls and authentication safeguards required by these regulations.

Mitigation Strategies

Disable GET method for credential submissions in the endpoint. Implement rate limiting on the /plugin/Live/api/preauthorize.json.php endpoint. Add account lockout mechanisms after multiple failed attempts. Ensure CSRF protection is enforced for all methods.
