CVE-2026-41011Network attack vector

Authenticated command execution via unescaped package name

Published Jun 4, 2026 · Updated Jun 4, 2026

OS command injection in BOSH before 282.1.12 allows remote authenticated users to execute commands on the Director through release upload. The PackagePersister.validate_tgz method interpolates a package name from release.MF into a tar command that Bosh::Common::Exec.sh passes to /bin/sh before model validation. Access requires bosh.releases.upload or bosh.admin and a new package fingerprint; injected commands run with the Director process's privileges.
