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. [5] [6] [7]
