Technical details

The administration API endpoints in Kentico Xperience 13 lack object-level authorization checks, allowing an authenticated attacker with access to the administration interface to retrieve restricted contact data via specially crafted requests. This is an insecure direct object reference (IDOR) vulnerability affecting versions 13.0.0 through 13.0.215. The issue requires prior authentication but allows attackers to escalate privileges and access data outside their permitted scope.
