As a result, an authenticated user without permission to access a data source can retrieve its connection details and credentials.\n\n\n\nSuccessful exploitation exposes sensitive data source information and may enable unauthorized access to the underlying databases using the disclosed credentials.\n\n\n\nThis 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.","published":"2026-10-08T09:16:42.000Z","lastModified":"2026-10-08T17:25:38.000Z","status":"Deferred","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00215,"percentile":0.11848,"date":"2026-10-26","history":[{"date":"2026-10-08","score":0.0015,"percentile":0.03633}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.21%).
