CVE-2020-28473 is a web cache poisoning vulnerability affecting the Bottle web framework (versions prior to 0.12.19) and its Debian packages. This medium-severity flaw (CVSS 6.8) allows attackers to manipulate how proxies and servers interpret requests using "parameter cloaking" via semicolons, leading to malicious responses being cached as legitimate. While the attack requires user interaction and high attack complexity, it can result in significant integrity and availability impacts. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
