Upgrade Chainguard python-3.9 to version 3.9.20-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python-3.9 package and not the python-3.9 package as distributed by Chainguard.
See How to fix? for Chainguard relevant fixed versions and status.
There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library module.
When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value.
