HighCVE-2025-3058

Xelion Webchat <= 9.1.0 - Authenticated (Subscriber+) Arbitrary Options Update

Xelion Webchat: Currently marked unpatched

Affected versions: *-9.1.0

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

The Xelion Webchat plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the xwc_save_settings() function in all versions up to, and including, 9.1.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
