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 · unedited
Capgo before 12.128.2 contains a denial of service vulnerability allowing attackers to register accounts using arbitrary email addresses without verification, then initiate deletion to lock emails in pending deletion state. Attackers can permanently lock legitimate users out of the platform for 30 days by exploiting unverified email ownership in account lifecycle operations.

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 · high confidence

Capgo before version 12.128.2 allows unauthenticated attackers to register accounts using arbitrary email addresses without verification. Attackers can initiate account deletion, which locks the email in a pending deletion state for 30 days, preventing legitimate owners from registering or accessing the platform during that period.

MitigationUpgrade to Capgo version 12.128.2 or later which implements proper email verification before allowing account lifecycle operations.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Capgo version
    Check the installed Capgo package version via your package manager or dependency file (package.json, Gemfile, etc.) for the @capgo/ or capgo package, or check the admin dashboard for the software version
    Affected if Version is earlier than 12.128.2
  2. Verify account registration email verification setting
    Inspect the Capgo authentication configuration or admin settings to determine whether newly registered accounts require email verification before becoming active
    Affected if Email verification is NOT enforced during account registration
  3. Confirm account deletion workflow
    Review the account lifecycle settings or API configuration to check if email ownership verification is required before processing an account deletion request
    Affected if Account deletion can be initiated without confirming the email is verified/owned by the requester
  4. Test pending deletion state behavior
    Create a test account with an arbitrary email address (not owned by you) and attempt to delete it, then observe if the email enters a 30-day pending deletion state
    Affected if The deletion proceeds and locks the unverified email in pending deletion for 30 days

You are affected if your Capgo version is before 12.128.2 and the account registration or deletion workflow does not enforce email verification before allowing lifecycle operations.

Generated from the published advisory. Verify against your own configuration.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to Capgo version 12.128.2 or later which implements proper email verification before allowing account lifecycle operations.

Recommended fix High confidence

12.128.2 or later

  1. Identify the current Capgo installation version by checking the application or package manager
  2. Review the release notes for version 12.128.2 to understand any changes or migration requirements
  3. Create a backup of current configuration and data before proceeding with the upgrade
  4. Upgrade Capgo to version 12.128.2 or later using the appropriate package manager or deployment method
  5. Verify the upgrade was successful by checking the new version number
  6. Confirm the vulnerability is resolved by testing that email verification is now required before account operations
