At a glance

CVE-2026-1254 is a medium-severity Missing Authorization vulnerability in the Modula Image Gallery WordPress plugin, affecting versions <= 2.13.6. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 2.13.7; sites on affected versions should update now. Disclosed February 2026, reported by type5afe.

Vulnerability Overview

The Modula Image Gallery – Photo Grid & Video Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.13.6. This is due to the plugin not properly verifying that a user is authorized to modify specific posts before updating them via the REST API. This makes it possible for authenticated attackers, with contributor level access and above, to update the title, excerpt, and content of arbitrary posts by passing post IDs in the modulaImages field when editing a gallery.

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.

CWE-862: Missing Authorization

Reaching this weakness in Modula Image Gallery <= 2.13.6 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 Modula Image Gallery the fix is 2.13.7: builds <= 2.13.6 are affected, anything from 2.13.7 onward is not.

Remediation

Update to version 2.13.7, 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: Modula Image Gallery 2.13.7 closes this, and updating the plugin is the step that ends it.
