Name of the Vulnerable Software and Affected Versions Weaver Xtreme Theme Support plugin for WordPress versions up to, and including, 6.4

Description The issue arises from insufficient input sanitization and output escaping on user-supplied attributes in the plugin's div shortcode, allowing authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages. These scripts will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 6.4, update to a version that addresses the insufficient input sanitization and output escaping issue in the div shortcode. As a temporary workaround, consider restricting access to the div shortcode for users with contributor-level access and above until a patch is available.
