Technical details
The vulnerability exists in the store contact form handling where user-supplied email addresses are placed directly in the From header instead of being validated or moved to a Reply-To header, allowing sender spoofing. An unauthenticated attacker can exploit this to make emails appear to originate from any address on the site's domain, bypassing SPF/DKIM protections that would normally prevent external spoofing. The attacker gains the ability to send phishing or social engineering messages to vendors impersonating trusted administrators.
