CVE-2022-31883Network attack vector

API key disclosure via unchecked object authorization

Published Jun 28, 2022 · Updated Aug 3, 2024

Insecure direct object reference in Marval MSM 14.19.0.12476 allows remote authenticated users to read other users' API keys. The API-key retrieval path accepts a user-controlled object reference and returns its key without verifying access to the referenced account. Low-privilege access is sufficient to retrieve administrator API keys, exposing credentials capable of authorizing requests with elevated permissions.
