CVE-2025-8887

Authenticated record disclosure via unchecked object keys

Published Oct 10, 2025 · Updated Jun 5, 2026

Authorization bypass in AYBS İnteraktif 2024 through 28082025 allows local users to read and alter records by supplying object keys. TR-CERT identifies user-controlled keys, missing authorization, forceful browsing, and parameter injection but does not name the affected endpoint or parameter. A low-privileged authenticated account is required; exploitation exposes sensitive information and permits limited record manipulation without interrupting service.
