Summary

The All in One SEO WordPress plugin before 5.0.0.1 does not sanitise and escape some content stored in posts before rendering it back in the post editor, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks that trigger when a higher privileged user edits the post.

Risk Assessment

An attacker can inject malicious scripts that execute when an administrator edits a post, potentially leading to admin account takeover or other damage.

Recommendation

Update the All in One SEO plugin to version 5.0.0.1 or later. Restrict roles that can edit posts to trusted users.
