Improper Preservation of Permissions vulnerability in Apache Airflow. This issue affects Apache Airflow from 2.8.2 through 2.8.3. Airflow's local file task handler in Airflow incorrectly set permissions for all parent folders of log folder, in default configuration adding write access to Unix group of the folders. In the case Airflow is run with the root user (not recommended) it added group write permission to all folders up to the root of the filesystem. If your log files are stored in the home directory, these permission changes might impact your ability to run SSH operations after your home directory becomes group-writeable. This issue does not affect users who use or extend Airflow using Official Airflow Docker reference images ( https://hub.docker.com/r/apache/airflow/ ) - those images require to have group write permission set anyway. You are affected only if you install Airflow using local installation / virtualenv or other Docker images, but the issue has no impact if docker…

# Patch Next advisory brief: CVE-2024-29735

Advisory: Apache Airflow Improper Preservation of Permissions vulnerability
IDs: CVE-2024-29735, GHSA-cff3-5qrp-hqx7
Record: https://patchnext.com/advisories/cve-2024-29735 (revision 2, source checked 26 Oct 2026, 13:13 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: apache-airflow 2.8.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI apache-airflow: affected >= 2.8.2, < 2.8.4; fixed in 2.8.4

## Suggested inspection (read-only)
- `python -m pip show apache-airflow`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on apache-airflow.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
