• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-19 · updated 2026-10-25
• Weakness: CWE-287

Description

Capgo before 12.128.2 contains a flaw in the Enforce Password Policy feature: after a Super Admin enables the policy and successfully changes their password to a compliant one, the backend does not update the password-compliance state. As a result, the backend continues to treat the account as non-compliant and repeatedly forces password-reset prompts, permanently locking the Super Admin out of organization access (organization lockout / denial of service) despite valid authentication.

Affected products

• Cap-go capgo: before 12.128.2 — fixed in 12.128.2

How to fix

Upgrade to a fixed version: Cap-go capgo 12.128.2. Check the vendor advisory for mitigations.
