Name of the Vulnerable Software and Affected Versions Product Subtitle for WooCommerce plugin for WordPress versions up to, and including, 1.3.9

Description The issue is related to Stored Cross-Site Scripting 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. The htmlTag parameter is specifically vulnerable to this type of attack.

Recommendations For versions up to, and including, 1.3.9, update to a version higher than 1.3.9 to resolve the issue. As a temporary workaround, consider restricting access to the htmlTag parameter to minimize the risk of exploitation.
