CVE-2024-29733 is a low-severity (CVSS 2.7) CWE-295 vulnerability in apache-airflow-providers-ftp. O3 Security confirms whether CVE-2024-29733 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apache Airflow FTP Provider: FTP_TLS instance with unverified SSL context
Real-World Exposure
apache-airflow-providers-ftpReal-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
Improper Certificate Validation vulnerability in Apache Airflow FTP Provider.
The FTP hook lacks complete certificate validation in FTP_TLS connections, which can potentially be leveraged. Implementing proper certificate validation by passing context=ssl.create_default_context() during FTP_TLS instantiation is used as mitigation to validate the certificates properly.
This issue affects Apache Airflow FTP Provider: before 3.7.0.
Users are recommended to upgrade to version 3.7.0, which fixes the issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for apache-airflow-providers-ftp. 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.
Fix
Update apache-airflow-providers-ftp to 3.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-29733 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether CVE-2024-29733 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 CVE-2024-29733. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
