CVE-2023-28640Network attack vector

Authenticated API-key disclosure via unchecked resource URL

Published Mar 27, 2023 · Updated Feb 19, 2025

Missing authorization in Apiman 3.0.0.Final allows remote authenticated users to read API keys through crafted Manager URLs. The Manager REST API key lookup uses organization, client, and client-version path values to fetch and return a key without verifying access to the named resource. A Manager account and correctly guessed identifiers are required; a disclosed key grants access only where that key is sufficient to use the protected API.
