LangGraph CLI prints the registry push token in langgraph deploy --verbose output
CVE-2026-115885 · GHSA-8prr-f582-jqq3
- Affected
- PyPI langgraph-cli >= 0.4.15, < 0.4.32
- Fixed in
- 0.4.32· Vendor fix available
- Issue
- `langgraph deploy --verbose` printed the temporary registry push token that the CLI uses to log Docker in to the deployment's image registry. Anyone who could read that output, for example in CI logs, could use the token until it expired. Details When Docker is available, `langgraph deploy` builds the image locally, requests a push token from LangSmith, and runs `docker login --password-stdin` with the token on stdin. The CLI's subprocess helper printed each command's stdin when verbose output was on, and the login step inherited `--verbose`, so the token was printed right after the `docker login` command line. `langgraph-cli` 0.4.15 through 0.4.31 are affected. Starting with 0.4.32, the login step runs without verbose output. Deploys run without `--verbose`, and deploys that build the image remotely, never printed the token. Impact You may be affected if you ran `langgraph deploy --verbose` with an affected version and the output was kept or shared, for example…
Recommended action: Upgrade to 0.4.32 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
