IBM dropped 19 Langflow CVEs in one batch. Nine score 9.8–9.9. All are RCE.

The frame that matters: Langflow *is* code execution. Every auth control is a gate in front of exec(). Nine gates failed. Four failure modes: absent gate (unauth RCE), too-narrow gate (missing authz), wrong-place gate (eval/exec injection), wrong-thing gate (code-gen control).

Patch target: 1.13.0. Earlier fixes at 1.12.4 and 1.12.5 don't cover the full batch.
