CVE-2025-59426 | lobe-chat has an Open Redirect

Exp

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.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.

Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
