Summary

wger: IDOR in nutritional_values endpoints exposes private dietary data via direct ORM lookup

Details

wger is a free, open-source workout and fitness manager. In versions up to and including 2.4, three nutritional_values action endpoints fetch objects via Model.objects.get(pk=pk) — a raw ORM call that bypasses the user-scoped queryset. Any authenticated user can read another user's private nutrition plan data, including caloric intake and full macro breakdown, by supplying an arbitrary PK. Commit 29876a1954fe959e4b58ef070170e81703dab60e contains a fix for the issue.
