What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Shopclass before 6.2.0 contains a stored cross-site scripting vulnerability that allows self-registered non-admin users to inject scripts into item listing descriptions when frontend TinyMCE is enabled. Attackers can submit malicious JavaScript, which ItemActions.php saves without tag stripping, causing it to execute in the site origin for any visitor viewing the listing.
