Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In Eclipse Dataspace Components from version 0.2.1 to 0.6.2, in the EDC Connector component ( https://github.com/eclipse-edc/Connector ), an attacker might obtain OAuth2 client secrets from the vault. In Eclipse Dataspace Components from version 0.2.1 to 0.6.2, we have identified a security vulnerability in the EDC Connector component ( https://github.com/eclipse-edc/Connector ) regarding the OAuth2-protected data sink feature. When using a custom, OAuth2-protected data sink, the OAuth2-specific data address properties are resolved by the provider data plane. Problematically, the consumer-provided clientSecretKey, which indicates the OAuth2 client secret to retrieve from a secrets vault, is resolved in the context of the provider's vault, not the consumer. This secret's value is then sent to the tokenUrl, also consumer-controlled, as part of an OAuth2 client credentials grant. The returned access token is then sent as a bearer token to the data sink URL. This feature is now disabled entirely, because not all code paths necessary for a successful realization were fully implemented.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix High confidence

Edc Connector >= 0.6.3

  1. Identify the current version of Edc Connector in use (must be >= 0.2.1 and < 0.6.3)
  2. Upgrade the Edc Connector to version 0.6.3 or later
  3. Verify the upgrade was successful by checking the component version
  4. Test the OAuth2 data sink functionality to confirm the vulnerable feature is disabled
  5. If OAuth2-protected data sinks are required, reconfigure with proper consumer-side vault integration after upgrade
Caveat The OAuth2-protected data sink feature is disabled in 0.6.3; any workflows relying on this functionality will need to be redesigned or use alternative authentication methods
