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.

h2 is a pure-Python implementation of a HTTP/2 protocol stack. Prior to version 4.3.0, an HTTP/2 request splitting vulnerability allows attackers to perform request smuggling attacks by injecting CRLF characters into headers. This occurs when servers downgrade HTTP/2 requests to HTTP/1.1 without properly validating header names/values, enabling attackers to manipulate request boundaries and bypass security controls. This issue has been patched in version 4.3.0.
