CVE-2026-43977

Descrição

wger is a free, open-source workout and fitness manager. In versions prior to 2.6, any authenticated user can read another user-s private workout session notes, exercise history, and training statistics by calling the /logs/ and /stats/ actions on a routine they do not own. The vulnerability exists in RoutineViewSet (wger/manager/api/views.py). The view defines two custom actions /logs/ and /stats/ that are intended to return data for the requesting user-s own training history within a routine. However, the underlying permission check (RoutinePermission.has_object_permission) grants read access to any authenticated user when the routine has is_template=True, regardless of ownership. When the /logs/ or /stats/ actions are invoked against a routine the attacker does not own, they return the owner-s private workout history, not the attacker-s. This issue has been fixed in version 2.6.
