This document contains information on how to report security vulnerabilities in Apache Airflow and how security issues reported to the Apache Airflow security team are handled. If you would like to learn more, head to the Airflow security documentation.

⚠️ Please do not file GitHub issues for security vulnerabilities as they are public! ⚠️

The Apache Software Foundation takes security issues very seriously. Apache Airflow specifically offers security features and is responsive to issues around its features. If you have any concern around Airflow Security or believe you have uncovered a vulnerability, we suggest that you get in touch via the e-mail address security@airflow.apache.org.

Before sending the report, however, please read the following guidelines first. The guidelines should answer the most common questions you might have about reporting vulnerabilities.

Only use the security e-mail address to report undisclosed security vulnerabilities in Apache Airflow and to manage the process of fixing such vulnerabilities. We do not accept regular bug reports or other security-related queries at this address. We will ignore mail sent to this address that does not relate to an undisclosed security problem in the Apache Airflow project. Please follow regular communication channels described in the Airflow Community page for inquiries, questions and other discussions related to the process or issues.

Specifically, we will ignore results of security scans that contain a list of dependencies of Airflow with dependencies in Airflow Docker reference image - there is a page that describes how the Airflow reference Image is fixed at release time and providing helpful instructions explaining how you can build your own image and manage dependencies of Airflow in your own image.

Please send one plain-text email for each vulnerability you are reporting including an explanation of how it affects Airflow security. We may ask that you resubmit your report if you send it as an image, movie, HTML, or PDF attachment when you could as easily describe it with plain text.

Before reporting vulnerabilities, please make sure to read and understand the security model of Airflow, because some of the potential security vulnerabilities that are valid for projects that are publicly accessible from the Internet, are not valid for Airflow.

Airflow is not designed to be used by untrusted users, and some trusted users are trusted enough to do a variety of operations that could be considered as vulnerabilities in other products/circumstances.

Again. Please make sure to read and understand the security model of Airflow - this might help to save your time for reporting and our time for assessing the issues when they are clearly expected, according to the Security model. You also avoid disappointment when you spend a lot of time on preparing the issue report to follow the guidelines above and what you get as a response is "this is not a security issue" or "this is invalid security issue" or "this is expected behaviour". You save time for yourself and for the Airflow Security team by reading and understanding the security model before reporting the issue.

Severity of the issue is determined based on the criteria described in the Severity Rating blog post by the Apache Software Foundation Security team.

Due to reasons explained in the previous chapter, some potential security vulnerabilities do not apply to Airflow, or have a different severity than some generic scoring systems (for example CVSS) calculation suggests. So we are not using any generic scoring system.

The Airflow Security Team will get back to you after assessing the report. You will usually get confirmation that the issue is being worked (or that we quickly assessed it as invalid) within several business days. Note that this is an Open-Source projects and members of the security team are volunteers so please make sure to be patient. If you do not get a response within a week or so, please send a kind reminder to the security team. We will usually let you know the CVE number that will be assigned to the issue and the severity of the issue as well as release the issue is scheduled to be fixed after we assess the issue (which might take longer or shorter time depending on the issue complexity and potential impact, severity, whether we want to address a whole class issues in a single fix and a number of other factors). You should subscribe and monitor the users@airflow.apache.org mailing list or announce@apache.org to see the announcement of the security issue - including the CVE number and the severity of the issue once the issue is fixed and release is public. Note that the announce@apache.org mailing list is moderated, and it might take a few hours for the announcement to appear there, so users@airflow.apache.org is the best place to monitor for the announcement.

Security issues in Airflow are handled by the Airflow Security Team. Details about the Airflow Security Team and how members of it are chosen can be found in the Contributing documentation.

Airflow core package is released separately from provider packages. While Airflow comes with constraints which describe which version of providers have been tested when the version of Airflow was released, the users of Airflow are advised to install providers independently of Airflow core when they want to apply security fixes found and released in providers. Therefore, the issues found and fixed in providers do not apply to the Airflow core package. There are also Airflow providers released by 3rd-parties, but the Airflow community is not responsible for releasing and announcing security vulnerabilities in them, this is handled entirely by the 3rd-parties that release their own providers.
