CVE-2026-55235

langgraph-api implements the LangGraph API for rapid development and testing. Prior to 0.10.0, langgraph-api permits a run or cron to specify a relative webhook target that is delivered through an in-process loopback transport, and the authentication middleware treats that transport as internal...

CVE-2026-55235

langgraph-api (the LangGraph Server runtime) prior to 0.10.0 allows a run or cron to specify a relative webhook target that is delivered through an in-process loopback transport. The authentication middleware treats this transport as internal, so the webhook reaches the server's own thread and ru...
