Name of the Vulnerable Software and Affected Versions Email Subscribers by Icegram Express – Email Marketing, Newsletters, Automation for WordPress & WooCommerce plugin for WordPress versions up to, and including, 5.7.14

Description The issue is related to Stored Cross-Site Scripting via a CSV import due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to, and including, 5.7.14, update to a version higher than 5.7.14 to resolve the issue. As a temporary workaround, consider restricting access to the CSV import feature to minimize the risk of exploitation. Additionally, ensure that unfiltered html is enabled, if possible, to reduce the attack surface.
