CVE-2026-58624Network attack vector

Authenticated arbitrary file write via JGit commands

Published Jul 20, 2026 · Updated Jul 20, 2026

Improper input validation in Apache MINA SSHD 2.0.0 through 2.18.0 and 3.0.0-M1 through 3.0.0-M4 allows remote authenticated users to write files. GitPgmCommandFactory accepts any JGit command from an SSH session, including git archive --output, which writes to an attacker-chosen server path. Exposure requires an authenticated SSH account and a server configured with GitPgmCommandFactory; servers without that factory are unaffected.
