Summary

This PR addresses a critical security vulnerability (CVE-2024-53391) in the tar-stream package that could allow directory traversal attacks during tar file extraction operations.

Vulnerability Details

  • CVE: CVE-2024-53391
  • Severity: Critical
  • Package: [email protected] (vulnerable version)
  • Impact: Malicious tar files could overwrite arbitrary files during extraction, potentially compromising system security

Fix Applied

Added a package resolution to force all dependencies to use the patched version:

"**/tar-stream": "^3.1.7"

This ensures that both direct and nested dependencies (via tar-fs and archiver packages) use the secure version of tar-stream.

Verification

  • Before: yarn list tar-stream showed both v2.2.0 (vulnerable) and v3.1.7
  • After: Only [email protected] is used throughout the dependency tree
  • Risk: Very low - [email protected] was already successfully used by other dependencies

Impact

  • Security: Eliminates critical directory traversal vulnerability
  • Compatibility: No breaking changes expected (v3.1.7 already in use by some dependencies)
  • Code Changes: Minimal - single line addition to package.json resolutions

This fix follows the established security vulnerability resolution patterns documented in our SECURITY.md and aligns with recent CVE fixes in the project changelog.
