This exploit chain is reachable only on sites where an administrator has created a custom wpForo secondary usergroup with a blank WordPress role and the 'mth' (Manage Themes) capability; on such sites, an attacker can self-register and claim that group via the unguarded wpforo_secondary_groupids[] POST field, bypassing the role-based group filter and gaining theme-management access as a Subscriber."
