Phishing content injection via unsanitized username parameter
Published Mar 19, 2026 · Updated Mar 19, 2026
Reflected HTML injection in SuiteCRM 7.15.0 allows remote attackers to alter the login page through a crafted username parameter. modules/Users/Login.php assigns default_user_name directly from the request to the login username, and the login templates render it without sanitization or escaping. No authentication is required, but a victim must open the crafted request; the injected markup supports phishing or page defacement.
