{"id":"CVE-2026-57111","summary":"Apache Helix REST: Permissive CORS Configuration in REST API Allows Unrestricted Cross-Origin","details":"Permissive Cross-Origin Resource Sharing (CORS) in the REST API (helix-rest, org.apache.helix.rest.server.filters.CORSFilter) in Apache Helix through 2.0.0 on all platforms allows a remote attacker controlling a web page visited by an authorized user to read responses from and issue cross-origin requests to administrative REST endpoints via a cross-origin request from an arbitrary origin, since the filter unconditionally returns Access-Control-Allow-Origin: * together with Access-Control-Allow-Credentials: true and reflects arbitrary Access-Control-Request-Method / Access-Control-Request-Headers values in preflight responses. Users are recommended to upgrade to version 2.0.1, which fixes this issue.","modified":"2026-10-08T02:48:18.056400946Z","published":"2026-07-09T07:09:05.827Z","database_specific":{"cwe_ids":["CWE-1385"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57111.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"last_affected":"2.0.0"}]}],"cna_assigner":"apache"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/08/11"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57111.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/wy2yv90lvqzx46vkg35xrtfddffq9cfj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57111"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/helix","events":[{"introduced":"0"},{"fixed":"300ca8435f3c958585f07fe64f21b3f9ad209ab4"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:apache:helix:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.0.1"}]}}],"versions":["helix-2.0.0","helix-1.3.1","helix-1.4.2","helix-1.4.1","helix-1.4.0","helix-1.3.0","helix-1.1.0","helix-1.0.4","1.0.1","helix-1.0.0","helix-0.9.3","helix-0.9.1","helix-0.8.4","helix-0.8.3","helix-0.8.2","helix-0.8.1","helix-0.8.0","helix-0.6.9","helix-0.6.8","helix-0.6.7","helix-0.6.6","helix-0.6.5","helix-0.6.4","helix-0.6.3","helix-0.6.2-incubating","helix-0.6.1-incubating"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57111.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
