GHSA-5w6h-pjw6-wvc6

MEDIUMFix: apache/airflow#64114

GHSA-5w6h-pjw6-wvc6 is a medium-severity (CVSS 5.4) Cross-Site Request Forgery (CSRF) vulnerability in apache-airflow-providers-keycloak. O3 Security confirms whether GHSA-5w6h-pjw6-wvc6 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

🐍apache-airflow-providers-keycloak

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

The Keycloak authentication manager in apache-airflow-providers-keycloak did not generate or validate the OAuth 2.0 state parameter on the login / login-callback flow, and did not use PKCE. An attacker with a Keycloak account in the same realm could deliver a crafted callback URL to a victim's browser and cause the victim to be logged into the attacker's Airflow session (login-CSRF / session fixation), where any credentials the victim subsequently stored in Airflow Connections would be harvestable by the attacker. Users are advised to upgrade apache-airflow-providers-keycloak to 0.7.0 or later.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for apache-airflow-providers-keycloak. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update apache-airflow-providers-keycloak to 0.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5w6h-pjw6-wvc6 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-5w6h-pjw6-wvc6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-5w6h-pjw6-wvc6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
