NVD Description

Note: Versions mentioned in the description apply only to the upstream airflow-2 package and not the airflow-2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Versions of the package cross-spawn before 6.0.6, from 7.0.0 and before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string.
