CVE-2026-18943: CWE-200 Information Exposure in WPC Admin Columns
The WPC Admin Columns WordPress plugin before 2.3.4 does not have authorisation checks in one of its AJAX actions, allowing users with a role as low as subscriber to read arbitrary user, post and term metadata, including data belonging to administrators.
AI Analysis
Technical Summary
CVE-2026-18943 is an information exposure vulnerability (CWE-200) in the WPC Admin Columns WordPress plugin versions prior to 2.3.4. The vulnerability arises because one AJAX action lacks proper authorization checks, enabling low-privilege users (subscribers) to read arbitrary metadata associated with users, posts, and terms. This can lead to unauthorized disclosure of sensitive administrative data.
Potential Impact
Unauthorized users with subscriber roles can access sensitive metadata belonging to administrators and other users, potentially leading to privacy violations and information leakage within the WordPress environment. There is no indication of active exploitation in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should upgrade to version 2.3.4 or later once available or apply any official fixes provided by the vendor. Until then, consider restricting subscriber access or disabling the affected AJAX functionality if possible.
