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.\n\nThis feature is now disabled entirely, because not all code paths necessary for a successful realization were fully implemented.\n\n","publishedAt":"2024-05-07T13:11:45.310Z","updatedAt":"2024-08-01T20:40:47.492Z","severity":{"score":6.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:L","source":"eclipse"},"assigner":"eclipse","products":["Eclipse Foundation EDC"],"affected":[{"vendor":"Eclipse Foundation","product":"EDC","packageName":"technology.edc","defaultStatus":"unaffected","versions":[{"version":"0.2.1","status":"affected","lessThanOrEqual":"0.6.2","versionType":"semver"}],"modules":["Connector"],"repo":"https://github.com/eclipse-edc/Connector"}],"references":["https://github.com/eclipse-edc/Connector/commit/a4e6018d2c0457fba6f672fafa6c590513c45d1b","https://github.com/eclipse-edc/Connector/releases/tag/v0.6.3","https://gitlab.eclipse.org/security/cve-assignement/-/issues/22","https://gitlab.eclipse.org/security/vulnerability-reports/-/issues/198"],"weaknesses":["CWE-201","CWE-522"],"ingestedAt":"2026-10-29T20:07:56.516Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/4xxx/CVE-2024-4536.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-4536","state":"PUBLISHED","datePublished":"2024-05-07T13:11:45.310Z","dateUpdated":"2024-08-01T20:40:47.492Z","assignerShortName":"eclipse","assignerOrgId":"e51fbebd-6053-4e49-959f-1b94eeb69a2c","dateReserved":"2024-05-06T07:05:31.518Z"},"containers":{"cna":{"title":"Eclipse EDC: OAuth2 Credential Exfiltration Vulnerability","descriptions":[{"lang":"en","value":"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.\n\nIn 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.
