CVE-2026-50881
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 · uneditedIncorrect access control in the impworks Bonsai v6.0 allows authenticated attackers with Editor privileges to escalate privileges to Administrator and execute unauthorized account, password, and configuration changes.
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 · moderate confidenceIncorrect access control in impworks Bonsai v6.0 allows authenticated users with Editor privileges to escalate to Administrator and modify accounts, passwords, and system configurations—likely due to missing or insufficient server-side authorization checks on sensitive operations.

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 installed Bonsai versionLocate the application version file, header, or admin panel 'About' section. In typical PHP applications like Bonsai, check the version in a config file, composer.json, or the admin dashboard under System Information or Settings.Affected if The installed version is v6.0 of impworks Bonsai.
-
Verify user role configuration existsAccess the admin panel and navigate to User Management or Roles settings. Confirm that Editor and Administrator roles are defined in the system.Affected if Editor and Administrator roles both exist in the role configuration.
-
Test Editor user access to admin functionsLog in with a user assigned only the Editor role. Attempt to access pages or endpoints for: 1) User account management, 2) Password reset/modification for other users, 3) System configuration settings. Observe whether these operations are permitted without a permission error.Affected if An Editor-role user can access or modify Administrator-only functions such as other user passwords, account settings, or system configuration.
-
Inspect server-side authorization checksReview application source code or API endpoints for sensitive operations (user management, password changes, config updates). Check if role verification occurs server-side before executing privileged actions. Look for missing permission checks on admin endpoints.Affected if Server-side code lacks role-based authorization validation for sensitive admin operations, allowing Editor users to execute them.
A user is affected if they run impworks Bonsai v6.0 with Editor-role accounts that can access Administrator-only functions due to missing server-side authorization checks.

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 and enforce role-based access control (RBAC) with server-side authorization validation to ensure Editor-role users cannot access Administrator-only functions, and audit all sensitive endpoints for proper permission checks.
