CVE-2025-51989Network attack vector

Phishing via unneutralized registration-email firstname

Published Aug 21, 2025 · Updated Jul 5, 2026

HTML injection in Evolution Consulting Kft. HRmaster v235 allows remote attackers to send phishing-capable HTML in registration emails. The public registration interface accepts HTML tags in the keresztnév (firstname) field and places that value into confirmation and job-application emails without neutralizing the markup. No account is required, and any previously unregistered email address can receive the crafted message, enabling phishing content to reach that recipient.
