{"schemaVersion":3,"id":"CVE-2026-93995","aliases":["UBUNTU-CVE-2026-93995","DEBIAN-CVE-2026-93995"],"status":"published","duplicateOf":null,"title":null,"description":"Improper input validation in sshd-git in Apache MINA SSHD, versions up to 2.19.0 and 3.0.0-M1 to 3.0.0-M5. Apache\nMINA SSHD is a Java library for client-side and server-side SSH.\n\n\n\n\nComponent org.apache.sshd:sshd-git provides though class GitPgmCommandFactory a way to configure an Apache MINA SSHD server such\nthat authenticated SSH clients can remotely execute git commands via the JGit library\non git repositories stored on the server. In CVE-2026-58624 this mechanism was restricted to only a few git commands, including \"git archive\" without \"--output\" or \"-o\" options such that the resulting archive would not be written on the server but instead sent back to the client over the SSH connection.\n\n\n\n\nThe fix done for CVE-2026-58624 was insufficient as it missed removing the single-argument \"-o=file.zip\" version of the command parameter from the \"archive\" command.\n\n\n\n\nUsers are recommended to upgrade to version 2.20.0 or 3.0.0-M6, which fix this issue.","dates":{"published":"2026-09-30T09:38:47.654Z","modified":"2026-09-30T14:30:58.296Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
