CVE-2026-56251 Capgo CVE debrief

Who should care

Defenders of Capgo instances, particularly those with admin-level users, should be aware of this vulnerability. The ability to elevate privileges from admin to super_admin makes this a high-priority issue for Capgo administrators. Security teams responsible for vulnerability management and patching should take immediate action to assess and mitigate this risk.

Technical summary

The vulnerability exists in Capgo versions before 12.128.2. Specifically, the row-level security policy in the org_users table is not properly enforced, allowing authenticated users with admin privileges to escalate their access to super_admin. This is a critical issue as it enables attackers to gain unauthorized super_admin access, potentially leading to full system compromise. The Common Vulnerability Scoring System (CVSS) score for this vulnerability is 7, indicating a high level of severity.

Defensive priority

High priority due to potential for privilege escalation and system compromise.

Recommended defensive actions

• Inventory Capgo instances to identify those running versions before 12.128.2.
• Review official advisories and documentation for Capgo to understand the vulnerability and necessary patches.
• Apply the latest patch (version 12.128.2 or later) to Capgo instances as soon as possible.
• Limit exposure by restricting access to critical systems and monitoring for suspicious activity.
• Verify that row-level security policies are properly configured and enforced in the org_users table.
