## Affected packages

- `apache-airflow` (PyPI): affected `>=2.4.0, <2.9.3`; fixed in `2.9.3`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Apache Airflow versions 2.4.0 up to but not including 2.9.3 are affected. An authenticated DAG author can craft the doc_md parameter so that arbitrary code runs in the scheduler context, which the Airflow security model forbids. Upgrade to Airflow 2.9.3 or later, which removes the vulnerability.

Written 5 Nov 2026.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-g5hv-r743-v8pm>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
