CVE-2026-24047

CVE-2026-24047 affects Backstage: @backstage/cli-common relies on resolveSafeChildPath in @backstage/backend-plugin-api, which before v0.1.17 failed to validate symlink chains and dangling symlinks. This allowed path traversal via symlink chains (e.g., link1 → link2 → /outside) and dangling symli...
