{"id":"CVE-2023-45286","aliases":["GHSA-xwh9-gc39-5298","GO-2023-2328"],"url":"https://o3.security/vulnerability/CVE-2023-45286","summary":"HTTP request body disclosure in github.com/go-resty/resty/v2","details":"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.","published":"2023-11-28T16:31:21.078Z","modified":"2026-07-15T01:48:50.178768671Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Go","name":"github.com/go-resty/resty/v2","fixedVersion":"2.11.0"}],"fix":{"url":"https://github.com/go-resty/resty/commit/577fed8730d79f583eb48dfc81674164e1fc471e","label":"go-resty/resty@577fed8"},"references":[{"type":"WEB","url":"https://pkg.go.dev"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2023-2328"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45286.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45286"},{"type":"REPORT","url":"https://github.com/go-resty/resty/issues/739"},{"type":"REPORT","url":"https://github.com/go-resty/resty/issues/743"},{"type":"FIX","url":"https://github.com/go-resty/resty/commit/577fed8730d79f583eb48dfc81674164e1fc471e"},{"type":"FIX","url":"https://github.com/go-resty/resty/pull/745"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:50.178768671Z"}}
