The reader in this package is a default bufio.Reader wrapping a net.Conn. It will read from the connection until it finds a newline. Since no limits are implemented in the code, a deliberately malformed V1 header could be used to exhaust memory in a server process using this code - and create a DoS. This can be exploited by sending a stream starting with PROXY and continuing to send data (which does not contain a newline) until the target stops acknowledging. The risk here is small, because only trusted sources should be allowed to send proxy protocol headers.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2021-23351","reference_id":"","reference_type":"","scores":[{"value":"0.00573","scoring_system":"epss","scoring_elements":"0.69171","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2021-23351"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23351","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23351"},{"reference_url":"https://github.com/pires/go-proxyproto/commit/7f48261db810703d173f27f3309a808cc2b49b8b","reference_id":"","reference_type":"","scores":[{"value":"4.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/pires/go-proxyproto/commit/7f48261db810703d173f27f3309a808cc2b49b8b"},{"reference_url":"https://github.com/pires/go-proxyproto/issues/69","reference_id":"","reference_type":"","scores":[{"value":"4.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/pires/go-proxyproto/issues/69"},{"reference_url":"https://github.com/pires/go-proxyproto/pull/71","reference_id":"","reference_type":"","scores":[{"value":"4.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/pires/go-proxyproto/pull/71"},{"reference_url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4BNVGJMVI3ZTZ675EFPUHPGXCKCGSX46","reference_id":"","reference_type":"","scores":[{"value":"4.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4BNVGJMVI3ZTZ675EFPUHPGXCKCGSX46"},{"reference_url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/C36IBVOZXRTWM7MGTRUTOM56P5RR74VU","reference_id":"","reference_type":"","scores":[{"value":"4.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/C36IBVOZXRTWM7MGTRUTOM56P5RR74VU"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2021-23351","reference_id":"","reference_type":"","scores":[{"value":"4.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-23351"},{"reference_url":"https://snyk.io/vuln/SNYK-GOLANG-GITHUBCOMPIRESGOPROXYPROTO-1081577","reference_id":"","reference_type":"","scores":[{"value":"4.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://snyk.io/vuln/SNYK-GOLANG-GITHUBCOMPIRESGOPROXYPROTO-1081577"},{"reference_url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985025","reference_id":"985025","reference_type":"","scores":[],"url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985025"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/44109?format=json","purl":"pkg:deb/debian/golang-github-pires-go-proxyproto@0.4.2-1?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-tmfv-qrj6-uqfz"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/golang-github-pires-go-proxyproto@0.4.2-1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/44108?format=json","purl":"pkg:deb/debian/golang-github-pires-go-proxyproto@0.4.2-3?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/golang-github-pires-go-proxyproto@0.4.2-3%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/44111?format=json","purl":"pkg:deb/debian/golang-github-pires-go-proxyproto@0.7.0-1?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/golang-github-pires-go-proxyproto@0.7.0-1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/44110?format=json","purl":"pkg:deb/debian/golang-github-pires-go-proxyproto@0.11.0-1?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://pub
