Pion DTLS versions v1.0.0 through v3.0.10 and 3.1.0 use random nonce generation with AES GCM ciphers, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging the reuse of a nonce in a session and a \"forbidden attack\". Upgrade to v3.0.11, v3.1.1, or later.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9},"cwes":["CWE-200"],"references":["https://github.com/pion/dtls/commit/61762dee8217991882c5eb79856b9e7a73ee349f","https://github.com/pion/dtls/commit/90e241cfec2985715efdd3d005972847462a67d6","https://github.com/pion/dtls/pull/796","https://github.com/pion/dtls/releases/tag/v3.0.11","https://github.com/pion/dtls/releases/tag/v3.1.1"],"products":["pion:dtls"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-26014","score":0.00697,"percentile":0.53074,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9f3f-wv7r-qc8r","url":"https://osv.dev/vulnerability/GHSA-9f3f-wv7r-qc8r","summary":"Pion DTLS's usage of random nonce generation with AES GCM ciphers risks leaking the authentication key","modified":"2026-09-10T03:50:34.689023565Z","packages":[{"ecosystem":"Go","name":"github.com/pion/dtls/v3","purl":"pkg:golang/github.com/pion/dtls/v3","ranges":[">=3.1.0 <3.1.1"],"fixed":["3.1.1"]},{"ecosystem":"Go","name":"github.com/pion/dtls/v2","purl":"pkg:golang/github.com/pion/dtls/v2","ranges":["<=2.2.12"],"fixed":[]},{"ecosystem":"Go","name":"github.com/pion/dtls","purl":"pkg:golang/github.com/pion/dtls","ranges":["<=1.5.4"],"fixed":[]},{"ecosystem":"Go","name":"github.com/pion/dtls/v3","purl":"pkg:golang/github.com/pion/dtls/v3","ranges":["<3.0.11"],"fixed":["3.0.11"]}]},{"id":"GO-2026-4479","url":"https://osv.dev/vulnerability/GO-2026-4479","summary":"Usage of random nonce generation with AES GCM ciphers risks leaking the authentication key in github.com/pion/dtls","modified":"2026-02-20T20:43:58.878828Z","packages":[{"ecosystem":"Go","name":"github.com/pion/dtls","purl":"pkg:golang/github.com/pion/dtls","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/pion/dtls/v2","purl":"pkg:golang/github.com/pion/dtls/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/pion/dtls/v3","purl":"pkg:golang/github.com/pion/dtls/v3","ranges":[">=3.0.10 <3.0.11",">=3.1.0 <3.1.1"],"fixed":["3.0.11","3.1.1"]}]}],"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).
