- Also known as: GHSA-XPH5-278P-26QX
- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.130.1
- Published: 2025-09-25 · Updated: 2025-09-25

## Affected

- lobehub lobe-chat: fixed in 1.130.1
- @lobehub/chat (npm): fixed in 1.130.1

## Description

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.
