⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal admin session cookies, redirect users to malicious sites, deface websites, or install malware on visitor systems through persistent script execution.
Likely Case
Attackers with contributor accounts inject malicious scripts that steal user session cookies or redirect users to phishing pages when they view coupon pages.
If Mitigated
With proper input validation and output escaping, the vulnerability is prevented, and only legitimate coupon codes are displayed without script execution.

Exploitation requires authenticated access but is straightforward once an attacker has contributor privileges. The vulnerability is well-documented in security advisories.
