Technical details
A type-confusion vulnerability in the `Members::update()` function incorrectly casts a CSV string parameter to an array before validation, producing an empty array that bypasses the secondary_groupids authorization guard. The downstream `encode()`/`decode()` functions correctly parse the original CSV string and persist the attacker-supplied group IDs to the database, allowing an authenticated attacker to inject the Admin group ID. Exploitation requires Subscriber-level access, at least 3 approved forum posts, and a valid wpforo nonce from the attacker's profile form.
