📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case

Likely Case
Attackers inject malicious scripts that steal user session cookies or credentials when users view manipulated product listings, leading to account compromise.
If Mitigated
With proper input validation and output encoding, the malicious payload would be rendered harmless as text rather than executable code.
🎯 Exploit Status
Requires ability to create or modify product names with malicious payload, then users must view the affected product listing.
