Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The @apostrophecms/import-export package in ApostropheCMS, versions before 3.7.1, can let import archives consume excessive server storage. Gzip extraction has no size or entry quotas and leaves artifacts behind when extraction or parsing fails, so a logged-in user importing archives can exhaust storage and cause denial of service. The source gives few details and notes that current exploitability still needs maintainer validation; upgrade to version 3.7.1.
