Summary

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.

Risk Assessment

The malicious script can execute in the browser of any visitor, potentially stealing session data or performing actions on behalf of the user. This may lead to admin account takeover.

Recommendation

Update Shopclass to version 6.2.0 or later. Consider disabling TinyMCE on the frontend until the update.
