CVE-2024-8261Network attack vector

Unauthenticated record disclosure via user-controlled key

Published Mar 3, 2025 · Updated Jun 2, 2026

Authorization bypass in Proliz Software OBS before 24.0927 allows remote attackers to read other users' records via a user-controlled key. The CNA identifies an IDOR in OBS that accepts a user-controlled record key without enforcing object-level authorization; no endpoint or parameter name is public. No authentication or user interaction is required, and the consequence is limited to disclosure of records reachable through the affected access-control path.
