Description
The CM Tooltip Glossary plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.9.20 due to insufficient input sanitization and output escaping. It does not escape some glossary_tooltip shortcode attributes. This makes it possible for Contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
