Name of the Vulnerable Software and Affected Versions WPC Smart Messages for WooCommerce versions prior to 4.2.9

Description Stored Cross-Site Scripting occurs due to insufficient input sanitization and output escaping on user-supplied attributes. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts through the text attribute of the wpcsm text rotator shortcode. These scripts execute whenever a user visits the affected page.

Recommendations Update to a version later than 4.2.8. As a temporary workaround, restrict the use of the text attribute within the wpcsm text rotator shortcode to trusted users only.
