GHSA-4H97-P9WQ-CHQJ
An early warning has been issued for a missing authorization check vulnerability in the Lemur package. This issue could allow authenticated users to export certificates they do not own.
What happened
The Lemur package reportedly has a missing authorization check on the POST /certificates/<id>/export endpoint for plugins with requires_key set to False. This vulnerability allows any authenticated user to export certificates they do not own. The issue has been flagged but has not yet been exploited in the wild. Users of affected versions should take immediate action to assess their exposure and apply necessary patches.
