Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Updates the unreviewed advisory for GHSA-h39j-r5qq-r9mm (decompress / CVE-2026-10732) to add richer OSV metadata and refresh scoring/references.

Changes:

  • Added a short summary and populated affected package/range information for npm decompress.
  • Updated severity representation to CVSS v4 vector only (and simplified the vector).
  • Adjusted references and expanded CWE mapping.

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
