Machine-written summary

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

The @apostrophecms/import-export package is affected in versions before 3.7.1. According to the original report, a contributor on an import-enabled localized content type can replace published content through archive duplicate handling. The source gives few details, and its follow-up review did not reproduce the issue on 3.7.0. Upgrade to @apostrophecms/import-export 3.7.1, the listed fixed version.
