CVE-2026-43977— wger IDOR: Authenticated Users Can Read Others' Private Workout Session Data via Template Routine API

wger IDOR: Authenticated Users Can Read Others' Private Workout Session Data via Template Routine API

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.

通过用户控制密钥绕过授权机制

wger 授权问题漏洞

wger是wger团队开源的一款自托管健身、营养和体重追踪器。 wger 2.6之前版本存在授权问题漏洞，该漏洞源于对RoutineViewSet中/logs/和/stats/操作的权限检查不当，导致已认证用户通过调用不属于自己的例程的/logs/和/stats/操作，可以读取其他用户私有的训练会话笔记、锻炼历史和训练统计数据。
