CVE-2026-123158 in openbsd openssh
The LogPulse agent checks every host for the vulnerable version of this software, so you see where the CVE is present.
What the vulnerability is
sshd in OpenSSH before 10.6p2 on Linux, when musl libc is used without PAM, lacks a workaround for a password authentication bypass (related to misinterpretation of whether a string is intended to be a password hash). For some configurations of accounts, any password between 256 and 1024 characters succeeds. An example of a platform using musl libc without PAM is Alpine Linux.
