Severity by source
AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N
sshd authentication is network-reachable (AV:N) and occurs pre-auth (PR:N) without user interaction; AC:H because non-default GSSAPI config and precise attempt sequencing are needed, yielding only low confidentiality impact.

In sshd in OpenSSH before 10.6, GSSAPIAuthentication authentication state can incorrectly be persisted across authentication attempts.
AnalysisAI
Information disclosure in OpenSSH sshd before 10.6 can occur when GSSAPIAuthentication is enabled and multiple authentication attempts are made, allowing authentication state from a prior attempt to persist. This is a low-priority issue despite affecting a ubiquitous product, because default OpenSSH configurations set GSSAPIAuthentication to no and exploitation also requires a functioning Kerberos/GSSAPI environment. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires sshd to be built with GSSAPI support and to have GSSAPIAuthentication explicitly enabled, which is NOT the default in OpenSSH (default is 'GSSAPIAuthentication no'), plus a functioning Kerberos/GSSAPI environment. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a low-priority issue despite affecting a ubiquitous product. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: OpenSSH 10.6. … Detailed patch versions, workarounds, and compensating controls in full report. |
