Upgrade Alpine:3.20 py3-django to version 3.1.7-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream py3-django package and not the py3-django package as distributed by Alpine.
See How to fix? for Alpine:3.20 relevant fixed versions and status.
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
