Prior to 0.62.6, the USERAUTH_REQUEST path reached from server::run_stream in russh/src/server/encrypted.rs increments self.common.auth_attempts but never compares it with server::Config.max_auth_attempts. An unauthenticated remote client can continue submitting authentication requests on one connection beyond the configured cap, bypassing the deployment's attempt-limiting policy and increasing online guessing opportunity and backend authentication workload. This issue is fixed in version 0.62.6.","state":0,"publishedAt":"2026-09-29T18:31:32.393+00:00","modifiedAt":"2026-09-30T19:29:26.432+00:00","affected":[{"ecosystem":"Vendor product","name":"russh","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eugeny\",\n                    \"product\": \"russh\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.62.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7,"severity":"LOW"}],"references":["https://github.com/Eugeny/russh/security/advisories/GHSA-g6xm-f9xp-qq35","https://github.com/Eugeny/russh/commit/f8fd0b11a393364dc7f01a182482d86adafdd653","https://github.com/Eugeny/russh/releases/tag/v0.62.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102825","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102825","identifiers":["CVE-2026-102825"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
