Apache · Apache Airflow · CVE-2023-36543
**Name of the Vulnerable Software and Affected Versions**
Apache Airflow versions prior to 2.6.3
**Description**
The issue is related to the use of a regular expression with inefficient computational complexity in Apache Airflow, which can be exploited by a remote attacker to cause a denial of service. An authenticated user can use crafted input to make the current request hang.
**Recommendations**
For versions prior to 2.6.3, upgrade to a version that is not affected to resolve the issue. As a temporary workaround, consider restricting access to the affected functionality to minimize the risk of exploitation.
