Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was identified in Dromara RuoYi-Vue-Plus up to 5.6.2. This issue affects the function FlwInstanceController/FlwDefinitionController/FlwCategoryController/FlwSpelController/TestLeaveController of the component Workflow Endpoint. Such manipulation leads to improper authorization. The attack can be launched remotely.
AnalysisAI
Improper authorization (broken access control) in Dromara RuoYi-Vue-Plus versions 5.6.0 through 5.6.2 allows authenticated low-privilege users to interact with protected Workflow module endpoints - FlwInstanceController, FlwDefinitionController, FlwCategoryController, FlwSpelController, and TestLeaveController - without the required authorization level. The vulnerability is remotely exploitable with no user interaction needed beyond holding a low-privilege account. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session with at minimum a low-privilege user account on the target RuoYi-Vue-Plus application (PR:L per CVSS 4.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) scores 5.3, reflecting network-reachable, low-complexity exploitation requiring only a low-privilege authenticated session. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a standard low-privilege account on a RuoYi-Vue-Plus 5.6.x deployment sends crafted HTTP requests directly to the workflow management REST endpoints, bypassing the authorization checks that should restrict these actions to higher-privileged roles such as workflow administrators. This allows the attacker to enumerate workflow definitions, modify workflow instances, or potentially submit expressions to the SpEL endpoint - all without the required privilege level. … |
| Remediation | No vendor-released patched version has been identified in the available data at time of analysis - affected versions are confirmed through 5.6.2 but a fixed release number is not provided by VulDB or EUVD references. … Detailed patch versions, workarounds, and compensating controls in full report. |
