High CVSS 8.8

CVE-2026-16617

NVD analysis in progress

The Simple File List WordPress plugin through 6.3.11 does not properly sanitise and escape a file's description before outputting it on the public file list, allowing unauthenticated users (when front-end file management is enabled) to perform Stored Cross-Site Scripting attacks that execute in the browser of any visitor viewing the list.

What this means

Exposure
Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
Weakness
Attacker-supplied script runs in other users’ browsers (cross-site scripting).
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.
