{"id":"CVE-2024-4536","aliases":["GHSA-2x52-8f29-7cjr"],"url":"https://o3.security/vulnerability/CVE-2024-4536","summary":"Eclipse EDC: OAuth2 Credential Exfiltration Vulnerability","details":"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. 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","published":"2024-05-07T13:11:45.310Z","modified":"2026-08-12T15:15:35.761545Z","cvss":{"score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.eclipse.edc:connector-core","fixedVersion":"0.6.3"}],"fix":{"url":"https://github.com/eclipse-edc/Connector/commit/a4e6018d2c0457fba6f672fafa6c590513c45d1b","label":"eclipse-edc/Connector@a4e6018"},"references":[{"type":"WEB","url":"https://github.com/eclipse-edc/Connector/releases/tag/v0.6.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/4xxx/CVE-2024-4536.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-4536"},{"type":"REPORT","url":"https://gitlab.eclipse.org/security/cve-assignement/-/issues/22"},{"type":"REPORT","url":"https://gitlab.eclipse.org/security/vulnerability-reports/-/issues/198"},{"type":"FIX","url":"https://github.com/eclipse-edc/Connector/commit/a4e6018d2c0457fba6f672fafa6c590513c45d1b"},{"type":"PACKAGE","url":"https://github.com/eclipse-edc/Connector"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T15:15:35.761545Z"}}
