CVE-2026-71807 RuoYi-Cloud-Plus CVE debrief

Who should care

Defenders responsible for RuoYi-Cloud-Plus deployments, particularly those using the ruoyi-workflow module, should assess exposure and prioritize mitigation to prevent unauthorized workflow executions and sensitive information disclosure.

Why it matters

CVE-2026-71807 allows authenticated low-privileged remote attackers to read sensitive workflow task details and trigger unauthorized workflow executions in RuoYi-Cloud-Plus <= 2.6.2. Defenders should verify and mitigate the vulnerability to prevent potential impacts.

• Potential unauthorized workflow executions
• Possible sensitive information disclosure
• Required verification of user roles and permissions
• Necessity to update or patch vulnerable RuoYi-Cloud-Plus versions

Technical summary

The vulnerability in RuoYi-Cloud-Plus <= 2.6.2, specifically in the ruoyi-workflow module, allows authenticated low-privileged remote attackers to read sensitive workflow task details and trigger unauthorized workflow executions due to lacking permission annotations in FlwTaskController and insufficient verification of user roles. The Service layer does not verify whether the current user is the task handler/related user. Authenticated low-privileged remote attackers can read sensitive workflow task details (/task/getTask/{taskId}) and trigger unauthorized workflow executions (/task/startWorkFlow). This issue can lead to potential unauthorized workflow executions and possible sensitive information disclosure.

Defensive priority

Defenders should prioritize verifying and mitigating the vulnerability in RuoYi-Cloud-Plus <= 2.6.2, particularly in the ruoyi-workflow module, to prevent unauthorized workflow executions and sensitive information disclosure.

Recommended defensive actions

• Verify and update RuoYi-Cloud-Plus to a version that addresses the vulnerability
• Restrict access to the ruoyi-workflow module to authorized users
• Monitor workflow executions and task details for suspicious activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability in RuoYi-Cloud-Plus <= 2.6.2. The vulnerability allows authenticated low-privileged remote attackers to read sensitive workflow task details and trigger unauthorized workflow executions.
