📄 Description (English)

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.

🤖 AI Executive Summary

wger fitness manager versions up to 2.4 contain an authorization bypass vulnerability allowing authenticated users to access other users' private nutrition plans through direct object references. The vulnerability affects nutritional_values endpoints that use raw ORM calls bypassing user-scoped querysets.
