Multiple cross-site scripting (XSS) vulnerabilities in ShopSite 8.1 and earlier allow remote attackers to inject arbitrary web script or HTML via the prevlocation parameter in shopper/sc/registration.cgi and other unspecified vectors.

ShopSite <= 1.5.10 - Cross-Site Request Forgery to Stored Cross-Site Scripting

The ShopSite plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.10. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

An arbitrary file upload vulnerability in the component /alsdemo/ss/mediam.cgi of ShopSite v14.0 allows attackers to execute arbitrary code via uploading a crafted SVG file.
