From version 0.34.0-beta.1 until version 0.64.0, its SSH server does not require the signature algorithm in a public-key authentication signature to match the algorithm named in the authentication request. A client possessing an authorized RSA private key can announce \u00A0rsa-sha2-512\u00A0 while supplying a valid \u00A0ssh-rsa\u00A0 SHA-1 signature, bypassing restrictions or producing misleading audit records when applications rely on the requested algorithm. A valid private-key signature remains required, and russh clients are not affected. This issue is fixed in version 0.64.0.","state":0,"publishedAt":"2026-11-05T21:18:35.607+00:00","modifiedAt":"2026-11-05T22:17:43.317+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":2.3,"severity":"LOW"}],"references":["https://github.com/Eugeny/russh/commit/a0ded76bdc352f8fbeaaeb175fb2a0c586fbc8f2","https://github.com/Eugeny/russh/pull/759","https://github.com/Eugeny/russh/releases/tag/v0.64.0","https://github.com/Eugeny/russh/security/advisories/GHSA-j7h2-66j4-ghjf"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-111062","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-347"],"productCriteria":[],"sourceDates":{"published":"2026-11-05T21:18:35.607","lastModified":"2026-11-05T22:17:43.317"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
