Summary
wger is a free, open-source workout and fitness manager. Prior to version 2.6, a user with only the `gym_trainer` permission can deactivate any account in the same gym, including `gym_manager` and `general_gym_manager` accounts. The `UserDeactivateView` grants access to anyone holding any one of `gym.manage_gym`, `gym.manage_gyms`, or `gym.gym_trainer` (OR logic via `WgerMultiplePermissionRequiredMixin`), and performs no privilege-hierarchy check to prevent a lower-privileged role from disabling a higher-privileged one. Version 2.6 fixes the issue.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
