CVE-2023-45286 Information

Description

A race condition in go-resty can result in HTTP request body disclosure across requests. This condition can be triggered by calling sync.Pool.Put with the same bytes.Buffer more than once when request retries are enabled and a retry occurs. The call to sync.Pool.Get will then return a bytes.Buffer that hasn’t had bytes.Buffer.Reset called on it. This dirty buffer will contain the HTTP request body from an unrelated request and go-resty will append the current HTTP request body to it sending two bodies in one request. The sync.Pool in question is defined at package level scope so a completely unrelated server could receive the request body.
