GHSA-c3qp-2ggw-xjg7 Shopper: Authorization bypass and RBAC privilege escalation in team settings

• Packagist shopper/framework: < 2.8.0 → fixed in 2.8.0

Impact Two distinct authorization defects in the team settings allowed any authenticated panel user to take over the RBAC system: • `Settings/Team/Index` had no `mount()` authorization. Any authenticated user could load the page and use its public actions to create new roles and delete other users, including administrators. • `Settings/Team/RolePermission` gated its write actions on the read-only `view_users` permission. Any user holding `view_users` could grant themselves or any other user arbitrary permissions, including `manage_users` and `edit_orders`, effectively escalating to full panel administrator from a read-only account. Combined, these two defects allow a low-privilege authenticated user to obtain administrator privileges and remove the legitimate administrators from the panel. Patches Fixed in `v2.8.0`: • `Settings/Team/Index::mount()` now authorizes against `manage_users`. • `Settings/Team/RolePermission` write actions now require `manage_users` instead of `view_users`. Upgrade via: ```bash composer require shopper/admin:^2.8 ``` Workarounds None. Upgrade to `v2.8.0`.
