CVE-2026-40474
Since GymConfig is an ownerless singleton, any authenticated user can modify the global gym configuration, triggering save() side effects that bulk-update user profile gym assignments — a vertical privilege escalation to installation-wide configuration…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
wger is a free, open-source workout and fitness manager. In versions 2.5 and below, the GymConfigUpdateView declares permission_required = 'config.change_gymconfig' but inherits WgerFormMixin instead of WgerPermissionMixin, so the permission is never enforced at runtime. Since GymConfig is an ownerless singleton, any authenticated user can modify the global gym configuration, triggering save() side effects that bulk-update user profile gym assignments — a vertical privilege escalation to installation-wide configuration control. This issue is fixed in version 2.5.
