Description

The Head Meta Data plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;head-meta-data&#39; post meta field in all versions up to, and including, 20251118 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
