Cache poisoning refers to a computer security vulnerability where invalid entries can be placed into a cache, which are then assumed to be valid when later used.
[1] Two common varieties are DNS cache poisoning[2] and ARP cache poisoning.
Web cache poisoning involves the poisoning of web caches[3] (which has led to security issues in programming languages, including all Python versions at the time in 2021, and expedited security updates[4]).
Attacks on other, more specific, caches also exist.
