CVE-2026-93995: Apache MINA SSHD improper input validation in sshd-git

CVE-2026-93995 · Severity: medium · CVSS 6.5 · Published 2026-09-30

Apache MINA SSHD is a Java library that enables SSH clients and servers to execute commands remotely. The sshd-git component allows authenticated users to run git commands on server repositories through a mechanism that was previously restricted for security. A flaw in the validation allows attackers to bypass these restrictions and write files to the server filesystem, potentially leading to data compromise or service disruption.

Technologies: Apache MINA SSHD. Vendors: Apache.

Technical details

An improper input validation flaw in the GitPgmCommandFactory component fails to properly block the single-argument "-o=file.zip" variant of git archive command parameters, allowing authenticated SSH clients to write output files to the server despite prior restrictions. The vulnerability affects versions up to 2.19.0 and 3.0.0-M1 through 3.0.0-M5, and requires prior SSH authentication to exploit.
