This can cause some minor information disclosure if a network-local attacker can inject messages during the handshake.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":[],"references":["https://go.dev/cl/724120","https://go.dev/issue/76443","https://groups.google.com/g/golang-announce/c/Vd2tYVM8eUc","https://pkg.go.dev/vuln/GO-2026-4340"],"products":["golang:go"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2025-61730","score":0.00324,"percentile":0.25448,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GO-2026-4340","url":"https://osv.dev/vulnerability/GO-2026-4340","summary":"Handshake messages may be processed at the incorrect encryption level in crypto/tls","modified":"2026-08-07T10:42:58.273913222Z","packages":[{"ecosystem":"Go","name":"stdlib","purl":"pkg:golang/stdlib","ranges":["<1.24.12",">=1.25.0 <1.25.6"],"fixed":["1.24.12","1.25.6"]}]}],"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).
