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.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-394"],"vendors":[],"products":[],"references":[{"url":"https://github.com/leonjza/sshhole-lab","tags":[]},{"url":"https://github.com/openssh/openssh-portable/commit/4353fdc43ef646c43a8dda7025cc1a898caf1482","tags":[]},{"url":"https://github.com/predkambrij/sshhole-repro","tags":[]},{"url":"https://hachyderm.io/@damienmiller/117563026759098135","tags":[]},{"url":"https://marc.info/?l=openssh-unix-dev&m=179388064263131&w=2","tags":[]},{"url":"https://news.ycombinator.com/item?id=50377976","tags":[]},{"url":"https://news.ycombinator.com/item?id=50378228","tags":[]},{"url":"https://www.openssh.org/releasenotes.html#10.6p2","tags":[]},{"url":"https://alpinelinux.org/posts/2026-11-05-openssh-password-authentication-bypass/","tags":[]},{"url":"https://github.com/google/goonami-scanner/pull/277","tags":[]},{"url":"https://news.ycombinator.com/item?id=50379704","tags":[]},{"url":"https://sshhole.com","tags":[]}],"exploitRefs":[{"url":"https://github.com/leonjza/sshhole-lab","tags":[]},{"url":"https://github.com/openssh/openssh-portable/commit/4353fdc43ef646c43a8dda7025cc1a898caf1482","tags":[]},{"url":"https://github.com/predkambrij/sshhole-repro","tags":[]},{"url":"https://github.com/google/goonami-scanner/pull/277","tags":[]}],"hasPoc":true,"ai":null}
