Description

This security bulletin contains information about 1 vulnerability.


1) Interpretation Conflict (CVE-ID: CVE-2026-106587)

CWE-ID: CWE-436 - Interpretation Conflict

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to potentially bypass intended authentication policy by causing a file lookup that should have been disabled.

The vulnerability exists due to incorrect interpretation of configuration values in sshd when a Match block overrides an option such as AuthorizedPrincipalsFile with the value of "none". A remote attacker can attempt authentication under the affected configuration to potentially have sshd consult a literal file named none instead of disabling the configured file source.
