CVE-2026-47744: Shopper: Authorization bypass and RBAC privilege escalation in team settings

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:

composer require shopper/admin:^2.8

Workarounds

None. Upgrade to v2.8.0.
