CVE-2026-56286
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 an authentication bypass vulnerability in the account deletion endpoint that allows deletion without password re-authentication or secondary verification. Attackers can delete user accounts via session hijacking, CSRF attacks, or parameter tampering, resulting in unauthorized account deletion, data loss, and denial-of-service.
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 contains an authentication bypass in the account deletion endpoint that fails to require password re-authentication or secondary verification. Attackers can exploit this via session hijacking, CSRF attacks, or parameter tampering to delete user accounts without proper authorization.

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.
-
Identify Capgo installation and versionLocate the Capgo CLI version via 'capgo --version' command, check package.json if self-hosted, or view the version displayed in the Capgo dashboard/account settings. Compare the installed version to the 12.128.2 threshold.Affected if The installed version is earlier than 12.128.2.
-
Confirm account deletion feature existsAccess the account settings or user profile section in the Capgo interface (web dashboard or CLI) and locate the account deletion or data deletion option. Verify this endpoint exists in the application.Affected if The account deletion feature is present and accessible to the user account.
-
Verify re-authentication requirement for account deletionAttempt to access or initiate the account deletion flow. Observe whether the application prompts for password re-entry, MFA verification, or any secondary confirmation before processing the deletion request.Affected if No password re-authentication or secondary verification is required before account deletion proceeds.
-
Inspect CSRF protection on sensitive endpointsReview the application or API configuration for CSRF token implementation. Check if the account deletion request includes and validates CSRF tokens, particularly for state-changing operations.Affected if CSRF tokens are missing or not validated on account deletion requests.
-
Review session integrity controlsExamine the session management configuration to determine if sessions are bound to IP address, user agent, or other integrity markers. Check if sessions can be reused across different contexts without re-validation.Affected if Sessions lack integrity checks and can be hijacked or reused without detection.
A user is affected if their Capgo installation is version 12.128.2 or earlier and the account deletion endpoint does not require password re-authentication or CSRF validation.

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.
dbcve · scopedUpgrade to Capgo version 12.128.2 or later which includes proper re-authentication requirements for account deletion. Additionally, implement CSRF tokens and validate session integrity to prevent the attack vectors described.
Capgo version 12.128.2 or later
- Upgrade Capgo to version 12.128.2 or later to remediate the authentication bypass vulnerability
- After upgrading, verify that the account deletion endpoint now requires proper authentication (password re-authentication or secondary verification)
- Test that legitimate account deletion workflows still function correctly with the new authentication requirements
- Monitor for any unexpected account deletion events after the upgrade
