Advisory
Source description from Wordfence Intelligence, credited to stealthcopter.
The Yoast SEO Premium plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions 25.7 to 25.9 due to a flawed regex used to remove an attribute in post content, which can be abused to inject arbitrary HTML attributes, including JavaScript event handlers. This vulnerability allows a user with Contributor access or higher to create a post containing a malicious JavaScript payload.
