## What is CVE-2026-41010?

CVE-2026-41010 is a high-severity command injection vulnerability in Cloud Foundry Foundation BOSH Director, published on 4 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

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:
- BOSH Director: all versions prior to v282.1.12 (inclusive); fixed in v282.1.12 or later

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

Check this codebase for CVE-2026-41010 and fix it if it is affected.

What it is: CVE-2026-41010 is a high-severity command injection vulnerability in Cloud Foundry Foundation BOSH Director, published on 4 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-41010 in the wild and no public exploit code.

Affected product: Cloud Foundry Foundation BOSH Director. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
