EUVD-2026-37583Severity by source
Network-accessible API requiring authenticated low-privilege account (PR:L); authorization bypass enables high-integrity impact via unauthorized write operations; confidentiality impact assessed as low since read operations may also be exposed.

AnalysisAI
Incorrect Authorization in Apache DolphinScheduler's experimental /v2 API interface permits authenticated users to invoke privileged operations without undergoing permission validation. All releases of the dolphinscheduler-api module prior to 3.4.2 are affected. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session on the Apache DolphinScheduler platform - an attacker must possess at least a low-privilege account credential. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | No CVSS vector, EPSS score, or KEV listing was provided for this CVE, limiting quantitative risk comparison. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who holds a low-privilege DolphinScheduler account (e.g., a data analyst with read-only permissions) discovers the undocumented `/v2` experimental API through source code review or endpoint enumeration. By directing standard administrative API calls - such as creating tenants, modifying datasource credentials, or altering workflow execution configurations - to the `/v2` path instead of `/v1`, the attacker bypasses the RBAC checks and successfully performs privileged operations. … |
| Remediation | The primary remediation is to upgrade to Apache DolphinScheduler version 3.4.2, which introduces proper authorization checks on the `/v2` API interface per the vendor's own recommendation. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all systems running DolphinScheduler API prior to version 3.4.2; implement network-level access restrictions to the /v2 endpoint limited to trusted administrators; review API access logs for suspicious /v2 activity. …
