Description
Huly Platform through 0.7.432 contains a missing authorization vulnerability that allows any authenticated user to merge arbitrary persons by calling the mergeSpecifiedPersons account RPC. Attackers knowing two person UUIDs can graft attacker-controlled unverified social ids onto a victim person, then use login or password recovery to take over the victim account.
