The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.99.1. This is due to missing or incorrect nonce validation on the 'proxy' function. This makes it possible for unauthenticated attackers to send the logged in user's cookies to their own server via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to Arbitrary File Write in versions up to and including 1.1.12. This is due to unsafe ZIP file extraction in the ampforwpsavelocalfont() function combined with inadequate cleanup that fails to remove nested directories and files. This makes it possible for authenticated attackers, with Author-level access and above, and permissions granted by an Administrator, to write arbitrary files to the server in a web-accessible location, potentially leading to remote code execution on hosts that execute PHP files in the uploads directory.

The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via Regex Transformation in all versions up to, and including, 1.1.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The crafted payload uses only WordPress-permitted comment tags and attributes (an anchor with href and title), and the AMP sanitizer pipeline omits javascript: protocol blocking, meaning neither the comment save filter nor the AMP output stage removes the malicious URI introduced by the transformation.

The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'amppbremovesavedlayoutdata' function in all versions up to, and including, 1.0.93.1. This makes it possible for authenticated attackers, with contributor access and above, to delete arbitrary posts on the site.

The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the disqusname parameter in all versions up to, and including, 1.1.1 due to insufficient input validation. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
