Apache Airflow vulnerable to sensitive information exposure when expose-config is set to non-sensitive-only

CVE-2023-45348GHSA-fpxx-xv4c-gxqp

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (apache-airflow 2.7.2), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Apache Airflow, versions 2.7.0 and 2.7.1, is affected by a vulnerability that allows an authenticated user to retrieve sensitive configuration information when the exposeconfig option is set to non-sensitive-only. The exposeconfig option is False by default. It is recommended to upgrade to a version that is not affected.

# Patch Next advisory brief: CVE-2023-45348

Advisory: Apache Airflow vulnerable to sensitive information exposure when expose-config is set to non-sensitive-only
IDs: CVE-2023-45348, GHSA-fpxx-xv4c-gxqp
Record: https://patchnext.com/advisories/cve-2023-45348 (revision 2, source checked 26 Oct 2026, 13:12 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: apache-airflow 2.7.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI apache-airflow: affected >= 2.7.0, < 2.7.2; fixed in 2.7.2

## 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.
