Open redirect via unvalidated X-Forwarded-Host header
Published Jun 17, 2026 · Updated Jun 17, 2026
Open redirect in eusonlito Password Manager before August 7, 2025 allows remote attackers to redirect users through crafted links. The application insufficiently validates X-Forwarded-Host when generating links, allowing an attacker-controlled domain to become the redirection target. Exploitation requires a victim to open the manipulated link; the resulting navigation supports phishing or deception but does not directly alter stored credentials or interrupt service.
