Description

WordPress Core is vulnerable to Denial of Service via Cache Poisoning in versions between 4.7.0 and 6.3.1. In cases where the X-HTTP-Method-Override header was sent in a request to a REST endpoint and the endpoint returned a 4xx error, the error could be cached, resulting in denial of service.
