Name of the Vulnerable Software and Affected Versions: Mosaic theme for WordPress versions up to, and including, 1.7.1

Description: The issue is related to Stored Cross-Site Scripting via the link parameter within the theme's Button shortcode due to insufficient input sanitization and output escaping. This allows authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 1.7.1, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the Button shortcode or disabling the link parameter within it until a patch is available.
