Summary
LibreChat versions prior to 0.8.1-rc2 contain a Server-side Request Forgery (SSRF) flaw in the "Actions" feature. An authenticated user with access to that feature can supply specially crafted OpenAPI specs and cause the LLM to invoke those actions, reaching URLs only the LibreChat server can access, such as cloud metadata services, which may allow impersonation of the server.
Mitigation
Fixed in version 0.8.1-rc2.
