Description
rConfig Core before 8.2.8 contains a privilege escalation vulnerability that allows authenticated users to assign arbitrary roles to any account by submitting an unvalidated role field through the Users API during user creation or profile updates. Attackers can exploit the missing allowlist validation and absent admin-level authorization check in StoreUserRequest to mass-assign the Admin role directly to the User model, granting access to privileged features. rConfig Pro and Enterprise are not affected.
