CVE-2026-94052

Estado: Pendiente de análisisCrítica (9.1)—

A missing check in LdapPasswordAuthenticator in component sshd-ldap in Apache MINA SSHD versions 1.2.0 to 2.19.0 or 3.0.0-M1 to 3.0.0-M5 bypassed authentication checks.

Apache MINA SSHD is a Java library for client-side and server-side SSH. The optional sshd-ldap component provides support for integrating password and publickey authentication on the server side with an LDAP server.

sshd-ldap is an optional component. SSH servers implemented with Apache MINA SSHD are affected only if they use sshd-ldap and do configure an LdapPasswordAuthenticator to be used for password authentication. Normal password authentication via the built-in mechanisms in sshd-core is _not_ affected by this vulnerability, which concerns only LdapPasswordAuthenticator.

Users are recommended to upgrade affected applications to version 2.20.0 or 3.0.0-M6, which fix this issue.
