Name of the Vulnerable Software and Affected Versions Favorites plugin for WordPress versions up to, and including, 2.3.2

Description The issue arises from insufficient input sanitization and output escaping on user-supplied attributes in the user favorites shortcode. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages, which will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.3.2, update to a version that addresses the insufficient input sanitization and output escaping issue in the user favorites shortcode. As a temporary workaround, consider restricting access to the user favorites shortcode for users with contributor-level and above permissions until a patch is available.
