WordPress Core, the software used to build websites, was vulnerable to a type of attack called a Denial of Service from Cache Poisoning in versions between 4.7.0 and 6.3.1. When a request was sent to a Rest Endpoint (a web address) and the endpoint returned an error, the error could be saved in the cache, which would result in the website not working properly.
