Descriptions

Auth. (admin+) Stored Cross-Site Scripting (XSS) vulnerability in Matt Gibbs Custom Field Suite plugin <= 2.6.2.1 versions.

The Custom Field Suite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via field values in versions up to, and including, 2.6.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only impacts multi-site installations and installations where unfiltered_html has been disabled.

Auth. (admin+) Stored Cross-Site Scripting (XSS) vulnerability in Matt Gibbs Custom Field Suite plugin <= 2.6.2.1 versions.
