Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-1368 is a vulnerability in the WordPress plugin "Video Conferencing with Zoom API" versions before 4.6.6. The issue arises because an AJAX handler in the plugin has its nonce verification disabled (commented out). This flaw allows unauthenticated attackers to send requests to the plugin\'s AJAX endpoint and obtain valid Zoom SDK signatures for any meeting ID.'}, {'type': 'paragraph', 'content': "Specifically, attackers can send unauthenticated POST requests with arbitrary Zoom meeting IDs to the endpoint wp-admin/admin-ajax.php using the action get_auth. The plugin then returns a JSON response containing a valid SDK signature and the site's Zoom SDK key without requiring any authentication."}, {'type': 'paragraph', 'content': 'This vulnerability is classified as an authentication bypass and falls under the OWASP Top 10 category A2: Broken Authentication and Session Management. It corresponds to CWE-287 (Improper Authentication).'}] [1]

Impact Analysis

This vulnerability can have significant security impacts because attackers can generate valid Zoom SDK signatures for any meeting ID without authentication.

With these signatures and the exposed Zoom SDK key, attackers might gain unauthorized access to Zoom meetings integrated via the plugin or manipulate meeting sessions.

Such unauthorized access could lead to privacy breaches, disruption of meetings, or exposure of sensitive information shared during those meetings.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to update the Video Conferencing with Zoom WordPress plugin to version 4.6.6 or later, where the nonce verification issue has been fixed.

Until the update can be applied, consider restricting access to the AJAX handler endpoint or disabling the plugin if possible to prevent exploitation.
