{"id":"UBUNTU-CVE-2026-94052","details":"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.","modified":"2026-10-08T12:55:04.743092236Z","published":"2026-09-30T10:17:00Z","upstream":["CVE-2026-94052"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-94052"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-94052"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2026/09/29/38"}],"affected":[{"package":{"name":"mina","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-11"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-11"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.7+dfsg-2","2.0.9-1","2.0.9-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina2-java","binary_version":"2.0.9-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-11","1.1.7.dfsg-12"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-12"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.16-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.16-2","binary_name":"libmina2-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-13"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.7.dfsg-13","binary_name":"libmina-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.19-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina2-java","binary_version":"2.0.19-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-13"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-13"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.4-2","2.1.5-1","2.1.5-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina2-java","binary_version":"2.1.5-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-13","1.1.7.dfsg-13ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-13ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1-3","2.2.1-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.2.1-3ubuntu0.1~esm1","binary_name":"libmina2-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94052.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/u
