User redirection via trusted X-Forwarded-Host
Published Jun 17, 2026 · Updated Jun 17, 2026
Open redirect in eusonlito Password Manager before 08/07/2025 allows remote attackers to redirect users via X-Forwarded-Host. The TrustProxies middleware trusts every proxy and honors X-Forwarded-Host when generating application URLs, while no TrustHosts middleware constrains accepted hosts. A targeted user must complete login or interact with the interface before the application sends the browser to the attacker-selected site, limiting direct impact to user redirection and associated confidentiality or integrity loss.
