  "title": "Trusted-proxy host header injection in bref/laravel-bridge",
  "summary": "bref/laravel-bridge versions before 3.1.7 trust all proxy addresses by default, allowing client-supplied forwarded host and prefix values to affect Laravel-generated URLs. An unauthenticated attacker may cause password-reset links to use an attacker-controlled host when the application does not enforce an expected URL root or trusted host policy.",
  "mitigation": "Upgrade bref/laravel-bridge to version 3.1.7 or later. Also configure Laravel to enforce the expected URL root or restrict trusted hosts, and avoid exposing direct origins where forwarded headers are not sanitized.",
