CVE-2026-56251
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 · uneditedCapgo before 12.128.2 contains a broken row level security policy in the org_users table that allows authenticated users to elevate privileges from admin to super_admin. Attackers can exploit the insufficient RLS enforcement to gain unauthorized super_admin access and compromise system security.
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 confidenceCapgo before 12.128.2 has a broken row level security policy on the org_users table that fails to properly enforce access controls. Authenticated users with admin privileges can exploit this insufficient RLS enforcement to escalate their own privileges to super_admin, bypassing intended permission boundaries.

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.
-
Check Capgo versionAccess the Capgo admin dashboard or use the API to retrieve the current installed version. Typically found in Settings > About or via CLI command: capgo --versionAffected if The installed version is lower than 12.128.2 (e.g., 12.128.1, 12.127.x, or earlier)
-
Verify RLS is enabled on org_users tableQuery the database to check if Row Level Security is enabled on the org_users table. In PostgreSQL: SELECT relname, relrowsecurity FROM pg_class WHERE relname = 'org_users';Affected if RLS returns as false or the query fails (RLS may not be implemented)
-
Inspect RLS policies on org_users tableQuery the database for existing RLS policies: SELECT policyname, cmd, qual, with_check FROM pg_policies WHERE tablename = 'org_users';Affected if No policies exist, or the policy uses permissive settings that allow bypassing role checks (e.g., missing WITH CHECK constraints on role fields)
-
Identify super_admin users in the systemQuery the org_users table to list all users with role = 'super_admin': SELECT id, email, role, org_id, created_at FROM org_users WHERE role = 'super_admin';Affected if Any user has super_admin role assigned, or there are unexpected role assignments that differ from expected organizational hierarchy
-
Check for recent privilege escalation changesReview audit logs or history tables for recent changes to the role column in org_users table, or compare current role assignments against known baselineAffected if There are recent changes to super_admin roles that were not initiated by existing super_admin accounts, or unauthorized role modifications are present
You are affected if your Capgo version is below 12.128.2 AND the org_users table lacks proper RLS policy enforcement, allowing admin users to obtain super_admin privileges.

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 dataUpgrade Capgo to version 12.128.2 or later. Additionally, review and correct the RLS policy on the org_users table to ensure proper enforcement of role-based access controls.
