How to fix?

Upgrade Debian:12 python-bottle to version 0.12.19-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-bottle package and not the python-bottle package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

The package bottle from 0 and before 0.12.19 are vulnerable to Web Cache Poisoning 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.
