CVE-2025-3058
Xelion Webchat <= 9.1.0 - Authenticated (Subscriber+) Arbitrary Options Update
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.
