CVE-2024-42490Network attack vector

Private-key disclosure via missing object authorization

Published Aug 22, 2024 · Updated Aug 22, 2024

Improper authorization in authentik before 2024.4.4 and 2024.6.0-rc1 through 2024.6.3 allows remote attackers to read private keys. Affected API actions disable normal filter backends, causing certificate, private-key, object-use, flow-execution, and service-state requests to skip the ObjectFilter authorization check. Exploitation requires a target object's identifier; certificate identifiers are unavailable to unprivileged users and are generally difficult-to-guess UUIDv4 values.
