At a glance

CVE-2026-12119 is a medium-severity Missing Authorization vulnerability in the Simple File List WordPress plugin, affecting versions <= 6.3.7. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 6.3.8; sites on affected versions should update now. Disclosed June 2026, reported by Chloe Chamberland.

Vulnerability Overview

The Simple File List plugin for WordPress is vulnerable to unauthorized file operations due to a missing authorization check on the 'frontmanage' shortcode attribute in all versions up to, and including, 6.3.7. This makes it possible for authenticated attackers, with contributor-level access and above, to perform arbitrary file operations including deletion, move, folder creation, and download. An attacker can create a draft post containing the 'eeSFL' shortcode, render it via the post preview endpoint to harvest the nonce needed to authorize the operations, and then submit file operation requests that bypass the intended authorization checks in includes/ee-list-ops-bar-process.php.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on integrity.

CWE-862: Missing Authorization

Simple File List <= 6.3.7 carries this weakness at frontmanage, and reaching it takes an account at Contributor level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Simple File List the fix is 6.3.8: builds <= 6.3.7 are affected, anything from 6.3.8 onward is not.

Remediation

Update to version 6.3.8, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Simple File List 6.3.8 closes this, and updating the plugin is the step that ends it.
