CVE-2026-94053

Authentication bypass via LDAP injection in component sshd-ldap in Apache MINA SSHD versions 1.2.0 to 2.19.0 and 3.0.0-M1 to 3.0.0-M5.<br /> <br /> <br /> <br /> <br /> Apache MINA SSHD is a Java library for client-side and server-side SSH. <br /> The optional sshd-ldap component provides support for integrating <br /> password and publickey authentication on the server side with an LDAP <br /> server.<br /> <br /> <br /> <br /> <br /> sshd-ldap is an optional component. SSH servers implemented with Apache <br /> MINA SSHD are affected only if they use sshd-ldap and do configure it to be used for password of public key authentication.<br /> <br /> Other Apache MINA SSHD servers are not affected.<br /> <br /> <br /> <br /> <br /> Lack of escaping LDAP filter metacharacters enabled successful authentication with username "*" and password "*".<br /> <br /> <br /> <br /> <br /> Users are recommended to upgrade affected applications to version 2.20.0 or 3.0.0-M6, which fix this issue by properly escaping filter parameters according to RFC 4515.
