AI Analysis
Technical Summary
CVE-2026-13158 is a CWE-434 vulnerability in the Everest Toolkit WordPress plugin through version 1.2.3.

Until a fix is available, restrict administrator privileges carefully and avoid using the demo-content import feature with untrusted content. Monitor official vendor channels for updates and apply patches promptly once released.
