CVE-2026-104751 is a medium-severity Missing Authorization vulnerability in the Rank Math SEO WordPress plugin, affecting versions < 1.0.280. 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 1.0.280; sites on affected versions should update now. Disclosed October 2026, reported by Duy Tran.

Vulnerability Overview

The Rank Math SEO – AI SEO Tools to Dominate SEO Rankings plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to 1.0.280 (exclusive). This makes it possible for unauthenticated attackers to perform an unauthorized action.

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 Rank Math SEO < 1.0.280 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 Rank Math SEO the fix is 1.0.280: builds < 1.0.280 are affected, anything from 1.0.280 onward is not.

Remediation

Update to version 1.0.280, 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: Rank Math SEO 1.0.280 closes this, and updating the plugin is the step that ends it.
