{"id":"DEBIAN-CVE-2026-56452","details":"Path traversal in the sshd-scp component of Apache MINA SSHD. Apache MINA SSHD is a Java library for client-side and server-side SSH.     The implementation of receiving files or directories via SCP did not validate filenames in SCP \"C\" or \"D\" commands. A malicious sender could send filenames containing paths, resulting in files to be written in attacker-controlled places.     The issue affects only    *  applications that use no longer supported Apache MINA SSHD versions \u003c 2.0.0 and use the SCP functions to receive files,   *  or applications using sshd-scp in Apache MINA SSHD \u003e= 2.0.0 to receive files.     Applications using Apache MINA SSHD \u003e= 2.0.0 not using sshd-scp are not affected.     The issue is fixed in Apache MINA 2.19.0 and 3.0.0-M5. Affected applications are advised to upgrade to these versions.","modified":"2026-09-14T17:03:20.675560476Z","published":"2026-07-20T21:16:48.820Z","upstream":["CVE-2026-56452"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-56452"}],"affected":[{"package":{"name":"libmina-sshd-java","ecosystem":"Debian:13","purl":"pkg:deb/debian/libmina-sshd-java?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.13.2-2","2.13.2-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-56452.json"}},{"package":{"name":"libmina-sshd-java","ecosystem":"Debian:14","purl":"pkg:deb/debian/libmina-sshd-java?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.13.2-2","2.13.2-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-56452.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
