{"id":"UBUNTU-CVE-2023-45286","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.","modified":"2026-01-20T18:09:20.976111Z","published":"2023-11-28T17:15:00Z","upstream":["CVE-2023-45286"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-45286"},{"type":"REPORT","url":"https://github.com/go-resty/resty/issues/743"},{"type":"REPORT","url":"https://github.com/go-resty/resty/issues/739"},{"type":"REPORT","url":"https://github.com/go-resty/resty/pull/745"},{"type":"REPORT","url":"https://pkg.go.dev/vuln/GO-2023-2328"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-45286"}],"affected":[{"package":{"name":"golang-github-go-resty-resty","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-resty-resty@2.4.0-1ubuntu1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.0-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-go-resty-resty-dev","binary_version":"2.4.0-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-45286.json"}},{"package":{"name":"golang-github-go-resty-resty","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-resty-resty@2.10.0-1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.0-1ubuntu1","2.10.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-go-resty-resty-dev","binary_version":"2.10.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-45286.json"}},{"package":{"name":"golang-github-go-resty-resty","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/golang-github-go-resty-resty@2.10.0-2?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.0-1","2.10.0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-go-resty-resty-dev","binary_version":"2.10.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-45286.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
