CVE-2026-56256: Capgo - Two-Factor Authentication Bypass via Organization Management API

• Severity: high (CVSS 7.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-24 · updated 2026-10-25
• Weakness: CWE-602

Description

Capgo before 12.128.2 enforces mandatory two-factor authentication only at the UI level. Sensitive Organization (ORG) management API endpoints (e.g., editing organization details, inviting users) do not validate 2FA completion on the backend. An authenticated Admin user who has not enabled 2FA can replay or modify a previously captured ORG API request to perform privileged organization actions, bypassing the globally enforced 2FA requirement.

Affected products

• Capgo: before 12.128.2 — fixed in 12.128.2

How to fix

Upgrade to a fixed version: Capgo 12.128.2. Check the vendor advisory for mitigations.
