Name of the Vulnerable Software and Affected Versions The Alert Box Block – Display notice/alerts in the front end. plugin for WordPress versions up to, and including, 1.1.2

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes in the plugin's Alert Box block. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages, which will execute when a user accesses an injected page.

Recommendations For versions up to, and including, 1.1.2, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the Alert Box block for users with contributor-level access and above until a patch is available.
