An authenticated user can supply the code of a project they are authorized to access together with a task definition code from another project, bypassing project access restrictions and modifying the target task definition and its upstream dependencies.\n\n\n\nThis vulnerability can compromise workflow integrity and disrupt task execution in unauthorized projects.This issue affects Apache DolphinScheduler: before 3.4.3.\n\n\n\nUsers are recommended to upgrade to version 3.4.3, which fixes the issue.","state":0,"publishedAt":"2026-10-08T08:18:19.41+00:00","modifiedAt":"2026-10-08T20:20:39.923+00:00","affected":[{"ecosystem":"https://repo.maven.apache.org/maven2","name":"org.apache.dolphinscheduler:dolphinscheduler-api","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache DolphinScheduler\",\n                    \"packageURL\": \"pkg:maven/org.apache.dolphinscheduler/dolphinscheduler-api\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"3.4.3\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://repo.maven.apache.org/maven2\",\n                    \"packageName\": \"org.apache.dolphinscheduler:dolphinscheduler-api\"\n                }"}],"metrics":[],"references":["https://lists.apache.org/thread.html/cn6v1m8pfnjn7rsqkq1xow8v63pw27w2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-66084","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-66084","identifiers":["CVE-2026-66084"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
