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.
