Summary

IBM Langflow OSS from 1.0.0 through 1.12.3 has improper authorization (CWE-285). An authenticated attacker can cancel any victim's running background workflow job with a single HTTP request, because no flow-level permission check is performed. The cancellation results in loss of in-progress compute work.
