High CVSS 7.2

CVE-2026-13158

NVD analysis in progress

The Everest Toolkit WordPress plugin through 1.2.3 does not validate the type of files uploaded during demo-content import (the WordPress file-type test is disabled), allowing high-privilege users (Administrator by default, including non-super-admin site administrators on multisite) to upload executable PHP files to the uploads directory.

What this means

Exposure
Exploitable remotely over the network, with a privileged account and with no action from the victim.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
Weakness
Upload accepts a dangerous file type, often one the server will execute.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.

Read automatically from the CVSS vector, the weakness type (CWE) and the EPSS score. The technical description above remains the one published by NIST.
