Summary

CVE Details

  • CVE-2026-87776: Denial of Service via memory leak on premature response close in the compression middleware. Fixed in compression 1.8.2.
  • CVSS: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

Test plan

  • Cherry-pick conflict resolved in package.json (release-2.2 resolutions preserved, compression added)
  • yarn why compression resolves all instances to 1.8.2
  • Commit GPG-signed and verified
  • CI passes

Add a yarn resolution to upgrade compression from 1.8.1 to 1.8.2,
fixing a DoS via memory leak when clients abort compressed responses.
