## Technical details

The vulnerability is an authorization bypass in the POST /api/ciphers/create endpoint on Entity Framework backends. When a UserId is nulled in requests, the server incorrectly treats the request as administrative, allowing attackers to inject vault items into read-only or inaccessible collections. Organization membership is the only precondition required to exploit this flaw.
