At a glance

CVE-2026-12557 is a medium-severity Missing Authorization vulnerability in the Ninja Forms - File Uploads WordPress plugin, affecting versions <= 3.3.29. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.3.30; sites on affected versions should update now. Disclosed July 2026, reported by Ad4m5.

Vulnerability Overview

The Ninja Forms - File Uploads plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.3.29. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to read all plugin debug log entries stored in the wp_nf3_log table or permanently delete all rows from that table.

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 privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in Ninja Forms - File Uploads <= 3.3.29 takes no account at all. 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 Ninja Forms - File Uploads the fix is 3.3.30: builds <= 3.3.29 are affected, anything from 3.3.30 onward is not.

Remediation

Update to version 3.3.30, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Ninja Forms - File Uploads 3.3.30 closes this, and updating the plugin is the step that ends it.
