{"cve":"CVE-2022-29222","nvd":{"published":"2022-05-21T00:15:12.047","modified":"2026-06-17T04:39:51.763","status":"Modified","description":"Pion DTLS is a Go implementation of Datagram Transport Layer Security. Prior to version 2.1.5, a DTLS Client could provide a Certificate that it doesn't posses the private key for and Pion DTLS wouldn't reject it. This issue affects users that are using Client certificates only. The connection itself is still secure. The Certificate provided by clients can't be trusted when using a Pion DTLS server prior to version 2.1.5. Users should upgrade to version 2.1.5 to receive a patch. There are currently no known workarounds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-295"],"references":["https://github.com/pion/dtls/commit/d2f797183a9f044ce976e6df6f362662ca722412","https://github.com/pion/dtls/releases/tag/v2.1.5","https://github.com/pion/dtls/security/advisories/GHSA-w45j-f832-hxvh","https://github.com/pion/dtls/commit/d2f797183a9f044ce976e6df6f362662ca722412","https://github.com/pion/dtls/releases/tag/v2.1.5"],"products":["pion:dtls"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-29222","score":0.00825,"percentile":0.57405,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w45j-f832-hxvh","url":"https://osv.dev/vulnerability/GHSA-w45j-f832-hxvh","summary":"Pion/DLTS Accepts Client Certificates Without CertificateVerify","modified":"2023-11-08T04:09:11.243676Z","packages":[{"ecosystem":"Go","name":"github.com/pion/dtls","purl":"pkg:golang/github.com/pion/dtls","ranges":["<2.1.5"],"fixed":["2.1.5"]},{"ecosystem":"Go","name":"github.com/pion/dtls/v2","purl":"pkg:golang/github.com/pion/dtls/v2","ranges":["<2.1.5"],"fixed":["2.1.5"]}]},{"id":"GO-2022-0462","url":"https://osv.dev/vulnerability/GO-2022-0462","summary":"Improper validation of client certificates in github.com/pion/dtls/v2","modified":"2024-05-20T16:03:47Z","packages":[{"ecosystem":"Go","name":"github.com/pion/dtls/v2","purl":"pkg:golang/github.com/pion/dtls/v2","ranges":["<2.1.5"],"fixed":["2.1.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
