This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake.","state":0,"publishedAt":"2026-02-05T18:16:10.857+00:00","modifiedAt":"2026-06-17T09:58:33.833+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10,"severity":"CRITICAL"},{"system":"CVSS 3.1 · 134c704f-9b21-4f2e-91b3-4a467353bcc0 · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":"CRITICAL"}],"references":["https://go.dev/cl/737700","https://go.dev/issue/77217","https://groups.google.com/g/golang-announce/c/K09ubi9FQFk","https://pkg.go.dev/vuln/GO-2026-4337"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-68121","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-295"],"productCriteria":["cpe:2.3:a:golang:go:*:*:*:*:*:*:*:*","cpe:2.3:a:golang:go:1.26.0:rc1:*:*:*:*:*:*","cpe:2.3:a:golang:go:1.26.0:rc2:*:*:*:*:*:*"],"sourceDates":{"published":"2026-02-05T18:16:10.857","lastModified":"2026-06-17T09:58:33.833"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
