Vulnerability Overview

The Site Offline plugin for WordPress is vulnerable to Maintenance Mode Bypass in versions up to, and including, 1.4.9. The presence of certain keywords in the URL allowed users to visit a site placed in maintenance mode thus bypassing the plugin's provided feature.

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-284: Improper Access Control

Reaching this weakness in Site Offline Or Coming Soon Or Maintenance Mode <= 1.4.9 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Site Offline Or Coming Soon Or Maintenance Mode the fix is 1.5.3: builds <= 1.4.9 are affected, anything from 1.5.3 onward is not.

Remediation

Update to version 1.5.3, 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: Site Offline Or Coming Soon Or Maintenance Mode 1.5.3 closes this, and updating the plugin is the step that ends it.
