CVE-2026-47366
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper verification of access permissions when modifying permissions through the Administration Control Panel (ACP) allowed an authenticated administrator to grant permissions beyond the level authorized for their account, resulting in privilege escalation within the administrative interface.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Administration Control Panel (ACP) fails to properly validate whether an authenticated administrator has sufficient privileges to grant specific permissions. By submitting permission modification requests through the ACP, a lower-privileged admin can assign themselves or others permissions exceeding what their account is authorized to manage, enabling privilege escalation within the administrative interface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if your system has an Administration Control Panel (ACP)Locate and access your system's admin interface, typically found at /admin, /acp, /administrator, or similar paths defined in your web server configuration. Confirm the presence of a permission or role management module within the ACP.Affected if Your system uses an ACP with permission management capabilities and you have administrator accounts with varying privilege levels.
-
Verify authorization enforcement on permission modification endpointsInspect the server-side code handling permission change requests in the ACP (look for request handlers for roles, permissions, or access control). Check that the code validates the requesting admin's privilege level BEFORE processing any permission modifications.Affected if The permission modification logic does not verify the requesting administrator has authority to grant the specific permission being requested.
-
Review admin audit logs for unauthorized permission changesSearch your application and system logs for events involving permission grants, role assignments, or access level modifications. Look for entries where a lower-privileged admin account modified permissions beyond their authorized scope.Affected if Audit logs show permission modifications performed by administrators whose own permissions should not allow them to grant such privileges.
-
Check for role-based permission boundaries in ACP configurationExamine your ACP permission management settings or database tables storing role-permission mappings. Verify that each admin role has clearly defined boundaries and that the system enforces these boundaries when permission requests are submitted.Affected if The system allows administrators to modify permissions outside their defined role boundaries without proper authorization checks.
-
Compare your admin role definitions against expected privilege constraintsReview all defined administrator roles and their assigned permissions in your system. Identify any roles that can modify permissions without restriction or that lack explicit authorization validation logic.Affected if Admin roles exist that can grant elevated permissions without the system validating the requester's own permission level for that specific action.
Your environment is affected if the ACP allows any authenticated administrator to modify permissions beyond what their role should authorize, without server-side validation of their privilege level.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement server-side authorization checks that verify the requesting administrator has the required permission-level authority before allowing any permission modifications, and enforce role-based permission boundaries in the ACP permission management logic.
