CVE-2026-106705 elunez CVE debrief

Who should care

Defenders and administrators of ELADMIN (eladmin-mp) instances, especially those with user roles that have the `roles:edit` permission, should assess exposure and verify role management functionality.

Why it matters

CVE-2026-106705 is a high-severity vulnerability in ELADMIN (eladmin-mp) that allows logged-in non-admin users with the `roles:edit` permission to modify their own role and assign arbitrary menu ids, potentially leading to unauthorized role modifications and privilege escalation.

• Potential unauthorized role modifications by logged-in non-admin users with the `roles:edit` permission.
• Possible escalation of privileges through arbitrary menu id assignments.
• Required verification of role management functionality and access controls.
• Need for additional monitoring and auditing of role changes.

Technical summary

The endpoint PUT /api/roles/menu (RoleController.updateRoleMenu) authorizes the request only by comparing the target role's level with the caller's minimum level, without validating the granted menu set or preventing a caller from modifying its own role. This allows a logged-in non-admin user with the `roles:edit` permission to modify their own role and assign arbitrary menu ids, potentially leading to unauthorized role modifications and privilege escalation. Defenders should prioritize verifying and restricting role management functionality, especially for users with the `roles:edit` permission.

Defensive priority

Defenders should prioritize verifying and restricting role management functionality, especially for users with the `roles:edit` permission.

Recommended defensive actions

• Verify and restrict role management functionality, especially for users with the `roles:edit` permission.
• Implement additional access controls to prevent unauthorized role modifications.
• Monitor and audit role changes 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 source item provide details on the improper access control vulnerability in ELADMIN (eladmin-mp). The vulnerability is caused by insufficient validation of the granted menu set and lack of prevention for a caller to modify its own role. A logged-in non-admin user with the `roles:edit` permission can submit its own role id together with an arbitrary list of menu ids. The source item provides CVE-2026-106705 details, and the CVE Program record provides official CVE metadata.
