Hi community,

Please find below the information about a vulnerability which has been 
addressed in Apache Airflow 2.0.2 and 1.10.15:

CVE-2021-28359: Apache Airflow Reflected XSS via Origin Query Argument in URL

Description:
The "origin" parameter passed to some of the endpoints like '/trigger' was 
vulnerable to XSS exploit. This issue affects Apache Airflow versions <1.10.15 
in 1.x series and affects 2.0.0 and 2.0.1 and 2.x series. 

This is the same as CVE-2020-13944 & CVE-2020-17515 but the implemented fix did 
not fix the issue completely. Update to Airflow 1.10.15 or 2.0.2. 

Please also update your Python version to the latest available PATCH releases 
of the installed MINOR versions, example update to Python 3.6.13 if you are on 
Python 3.6. (Those contain the fix for CVE-2021-23336 - 
https://nvd.nist.gov/vuln/detail/CVE-2021-23336).
