CVE-2025-3058: CWE-862 Missing Authorization in jauharixelion Xelion Webchat
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.
AI Analysis
Technical Summary
CVE-2025-3058 is a missing authorization vulnerability (CWE-862) in the Xelion Webchat WordPress plugin affecting all versions up to 9.1.0. The issue arises from the lack of a capability check in the xwc_save_settings() function, permitting authenticated users with low privileges (Subscriber-level and above) to update arbitrary WordPress options. Attackers can exploit this to change the default registration role to administrator and enable user registration, effectively escalating their privileges to full administrative access on the site.
Potential Impact
Successful exploitation allows authenticated low-privilege users to escalate their privileges to administrator by modifying WordPress settings. This compromises site integrity, confidentiality, and availability by granting attackers full administrative control, including the ability to create new admin users and alter site configurations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to trusted users only and consider disabling or removing the Xelion Webchat plugin if possible to prevent exploitation.
