Is your app affected by CVE-2025-67895?
Paste this prompt into Claude Code, Cursor or any AI coding tool: it runs a free Shippable scan of your project and fixes what it finds. Built with Lovable, Bolt or v0? Scan your live app. Or upload your package file.
Who is affected
apache-airflow-providers-edge3(PyPI) < 2.0.0
How to check
- Run
pip show apache-airflow-providers-edge3in your project to see the installed version, including copies pulled in by other packages. - Or paste your lockfile into the checker: it lists every package with a known vulnerability, this one included.
- Or run
npx shippable-dev scan localhost:3000in your project folder. It reads your lockfile and flags this vulnerability along with every other known one.
How to fix
Copies a prompt for Claude Code, Cursor or Codex: it checks your lockfiles for this and upgrades it.
- Upgrade
apache-airflow-providers-edge3to 2.0.0 or later, commit the lockfile and redeploy. - If a vulnerable version was live, check your logs and rotate the secrets that server could read.
The advisory
Edge3 Worker RPC RCE on Airflow 2.
This issue affects Apache Airflow Providers Edge3: before 2.0.0 - and only if projects installed and configured it on Airflow 2.
The Edge3 provider support in Airflow 2 has been always development-only and not officially released, however if projects installed and configured Edge3 provider in Airflow 2, it implicitly enabled non-public (normally) API which was used to test Edge Provider in Airflow 2 during the development. This API allowed Dag author to perform Remote Code Execution in the webserver context, which Dag Author was not supposed to be able to do.
If projects installed and configured Edge3 provider for Airflow 2, they should uninstall it and migrate to Airflow 3. The new Edge3 provider versions (>=2.0.0) has a minimum version of Airflow set to 3 and the RCE-prone Airflow 2 code is removed, so it should no longer be possible to use the Edge3 provider 2.0.0+ on Airflow 2.
If projects used Edge Provider in Airflow 3, you they are not affected.
Check your whole app
Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
