CVE-2026-41010

CVSS v3.1

8.2

High

VectorAV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
ReleaseJob#unpack builds job dir = File.join(@release dir, 'jobs', name) and job tgz = File.join(@release dir, 'jobs', "#{name}.tgz") where name returns @job meta['name'], a value taken verbatim from the jobs: array of the attacker-supplied release.MF inside the uploaded tarball. These paths are then interpolated into a shell string: Bosh::Common::Exec.sh("tar -C #{job dir} -xf #{job tgz} 2>&1", :on error => :return). Bosh::Common::Exec.sh executes via %x{#{command}} (bosh-common/lib/bosh/common/exec.rb:53), i.e. /bin/sh -c, so any shell metacharacters in name are interpreted. FileUtils.mkdir p(job dir) on line 49 creates the literal directory (no shell) and succeeds even when the name contains $()/;, so execution reaches the sh call.
Affected versions:
