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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-102825)\n\nAffected packages:\n\n- `russh <= 0.62.5`\n\nPatched in:\n\n- `russh 0.62.6`\n\nSource: https://github.com/advisories/GHSA-g6xm-f9xp-qq35\n\n## Vendor advisories\n\n- **RHSA-2026:74586** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-01 · [advisory](https://access.redhat.com/errata/RHSA-2026:74586)","depth":"twilight","depthScore":32,"depthScoreParts":{"impact":20.4,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":213934,"id":"CVE-2026-102825","ts":1790799886540,"field":"exploit_available","old":"false","new":"true"}]}
