The endpoint does not enforce the write permission required for this operation, allowing the user to make unauthorized changes to workflow instances.\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.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://lists.apache.org/thread/lt35p8xc1w7ovgq68g4zz1c8vnk5ow6o","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/29/21","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
