What is CVE-2026-18943?

The WPC Admin Columns plugin for WordPress prior to version 2.3.4 lacks proper authorization checks in one of its AJAX actions. This oversight permits users with minimal roles, such as subscribers, to access and read arbitrary user, post, and term metadata, potentially exposing sensitive information, including data associated with higher-level administrators.

Affected Version(s)

WPC Admin Columns 0 < 2.3.4

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
