CVE-2024-4536

OAuth2 secret disclosure via provider-vault key resolution

Published May 7, 2024 · Updated Aug 1, 2024

Credential disclosure in Eclipse EDC 0.2.1 through 0.6.2 allows remote authenticated users to read OAuth2 secrets via sink properties. The provider data plane treats the consumer-controlled clientSecretKey as a key in the provider vault, then sends the resolved secret to the consumer-controlled tokenUrl. A highly privileged dataspace participant must configure a custom OAuth2-protected sink; disclosure is limited to secrets referenced by keys present in the provider vault.
