📄 Description (English)

The Pinterest Site Verification plugin using Meta Tag plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post_var' parameter in versions up to, and including, 1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

🤖 AI Executive Summary

The Pinterest Site Verification plugin for WordPress contains a Stored XSS vulnerability in versions up to 1.8 that allows authenticated subscribers to inject malicious scripts via the 'post_var' parameter. These scripts execute when users access affected pages, potentially compromising user sessions and data.
