CVE-2026-56251

Capgo - Privilege Escalation via Broken Row Level Security in org_users

Published Jun 21, 2026 CVSS 4.0 · 7 High EPSS < 1% KEV · Not listed
Description
Capgo 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.

Analysis

AI-generated

Technical impact

Capgo versions prior to 12.128.2 contain a broken row‑level security policy on the org_users table. The policy fails to restrict users with admin privileges from accessing records belonging to super_admin accounts. As a result, an attacker who has already authenticated as an admin can elevate their access level to super_admin, granting full system control and the ability to modify or delete critical data. The weakness is a classic privilege escalation scenario rooted in inadequate access controls (CWE‑266).

Affected Systems

The vulnerability affects the Capgo application (Capgo:Capgo). No specific affected versions are listed beyond the claim that all releases before 12.128.2 are vulnerable, so any deployment running a pre‑12.128.2 version is at risk.

Risk and Exploitability

The CVSS score of 7 indicates a moderate severity. No EPSS value is published and the issue is not listed in CISA’s KEV catalog, suggesting limited known exploitation. The attack requires the attacker to be an authenticated admin user; once authenticated, the attacker can exploit the insufficient RLS enforcement to gain super_admin rights. The nature of the flaw allows exploitation without elevated network privileges or additional exploits.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Capgo release (12.128.2 or newer) to resolve the RLS flaw.
  • If immediate patching is not possible, temporarily disable or lock super_admin accounts until the patch can be deployed.
  • Review and harden row‑level security policies on the org_users table to ensure that non‑super_admin users cannot access super_admin records.
