Shopp 18.104.22.168 is available now.
It is a security release for all previous Shopp versions. The release addresses a security vulnerability related to catalog searches.
The issue was discovered with automated security scans reported to us from an individual in our community.
We urge you to update to 22.214.171.124 promptly, especially if you use Shopp accounts integrated with WordPress users in combination with the Shopp search widget or the
shopp('catalog','search') Theme API template tag.
If you run custom add ons or have modified official Shopp add ons, be sure to backup your modifications before updating.
For Shopp access key owners, download manually from your Shopp Store Account Dashboard or from your WordPress/Shopp website (with an activated Shopp access key) from the WordPress Admin → Plugins manager.
