Technical details
The plugin's `maybe_add_role_to_user()` function re-assigns cached roles from the `dfxwcrc_foreign_roles` user meta without validating that the external provider still grants those roles. The `remember_foreign_roles()` function merges new roles into the cache but never removes revoked ones, allowing revoked administrator roles to persist. When triggered (e.g., on product purchase in Replace Roles mode), the cached administrator role is restored, granting full site access to an authenticated attacker whose role was previously revoked by an external provider.
