CVE-2025-62928

Vulnerability

Overview

The SEO Meta Description Updater plugin for WordPress, versions up to and including 1.2.0, contains a missing authorization vulnerability classified as Missing Authorization (Broken Access Control). This flaw stems from the plugin's failure to properly verify user permissions or nonce tokens before executing certain higher-privileged actions. As a result, the plugin exposes functionality that should be restricted to authorized users, such as administrators, to any unauthenticated or lower-privileged user [1].

Exploitation and

Attack Surface

Attackers can exploit this vulnerability without needing any special authentication or elevated privileges. The missing authorization checks mean that any user, including unauthenticated visitors, can trigger functions that modify SEO meta descriptions. This type of vulnerability is commonly targeted in mass-exploit campaigns, where attackers automate attacks against thousands of WordPress sites regardless of their size or popularity [1].

Impact

Successful exploitation allows an attacker to alter or delete SEO meta descriptions for posts and pages. This can lead to defacement of search engine results, damage to the site's SEO ranking, and potential redirection of traffic. The integrity of the site's content management is compromised, and the attacker gains the ability to perform actions that should be reserved for site administrators [1].

Mitigation

The vendor has not released a patched version beyond 1.2.0, and the plugin may be considered end-of-life. Users are strongly advised to update the plugin immediately if a newer version becomes available. If updating is not possible, site owners should contact their hosting provider or web developer for assistance. As an immediate workaround, disabling the plugin until a fix is applied is recommended [1].
