CVE-2026-41011 (GCVE-0-2026-41011)

Vulnerability from cvelistv5 – Published: 2026-06-04 02:26 – Updated: 2026-06-04 02:26
VLAI
Summary
PackagePersister.validate_tgz builds "tar -tf #{tgz} 2>&1" where tgz = File.join(release_dir, 'packages', "#{name}.tgz") and name = package_meta['name'] comes directly from release.MF inside the uploaded tarball. The string is passed to Bosh::Common::Exec.sh, which executes via %x{} — i.e., /bin/sh -c. No Shellwords.escape is applied. The Models::Package Sequel validation (VALID_ID = /^[-0-9A-Za-z_+.]+$/i) would reject the name, but in create_package (lines 74–79) the shell-out in save_package_source_blob runs before package.save, so validation fires too late. Affected versions: - BOSH: all versions prior to v282.1.12 (inclusive); fixed in v282.1.12 or later
