Name of the Vulnerable Software and Affected Versions The Email Customizer for WooCommerce versions up to and including 2.6.7

Description The Email Customizer for WooCommerce plugin for WordPress is susceptible to Stored Cross-Site Scripting through email template content. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level access to inject arbitrary web scripts into email templates. These scripts will execute when customers view transactional emails. This issue only impacts multi-site installations and those where unfiltered html has been disabled.

Recommendations Update The Email Customizer for WooCommerce plugin to a version later than 2.6.7.
