…-mp2f-45pm-3cg9 The unmaintained 'decompress' package (<=4.2.1) has a critical path traversal vulnerability (CVE-2026-53486 / GHSA-mp2f-45pm-3cg9). No upstream fix exists. Migrate packages/mongodb-downloader to the maintained fork @xhmikosr/decompress v11.1.3, which resolves symlink/hardlink escape, path containment prefix issues, and setuid/setgid bit preservation. Changes: - Replace 'decompress' direct dep with '@xhmikosr/decompress@^11.1.3' in packages/mongodb-downloader/package.json - Remove @types/decompress (no longer needed for 'decompress' module) - Add local type declaration src/xhmikosr-decompress.d.ts - Update import in src/index.ts to '@xhmikosr/decompress' - Update package-lock.json Fixes Dependabot alert #293 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Remove@types/decompressfromdevDependencies(the type declarations are now provided locally).packages/mongodb-downloader/src/xhmikosr-decompress.d.ts(new): local ambient type declaration for@xhmikosr/decompress(the package ships no bundled types and there is no@types/xhmikosr__decompresson npm).packages/mongodb-downloader/src/index.ts: update import from'decompress'→'@xhmikosr/decompress'.package-lock.json: updated transitively —decompress@4.2.1and its plugins (decompress-tar,decompress-tarbz2,decompress-targz,decompress-unzip) are replaced by the@xhmikosrequivalents.The call-site API (
decompress(filename, outputDir, { strip, filter })) is unchanged;@xhmikosr/decompressis a drop-in replacement.
