# CVE-2025-59426

> 4.3 MEDIUM · 🧪 PoC

## Beschreibung

Lobe Chat is an open-source artificial intelligence chat framework. Prior to version 1.130.1, the project's OIDC redirect handling logic constructs the host and protocol of the final redirect URL based on the X-Forwarded-Host or Host headers and the X-Forwarded-Proto value. In deployments where a reverse proxy forwards client-supplied X-Forwarded-* headers to the origin as-is, or where the origin trusts them without validation, an attacker can inject an arbitrary host and trigger an open redirect that sends users to a malicious domain. This issue has been patched in version 1.130.1.
