python-bottle before 0.12.19 is 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 (CVE-2020-28473).");
