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 an unsecured images bucket lacking any row level security controls, allowing unauthenticated attackers to read, insert, and delete stored app icons. Remote attackers can exploit this misconfiguration to delete all icons and leak sensitive app IDs and user IDs.

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 has an unsecured cloud storage bucket for app icons that lacks both authentication requirements and row-level security controls. Unauthenticated remote attackers can read, insert, and delete icon files, enabling them to delete all stored icons and exfiltrate sensitive app IDs and user IDs embedded in the stored data.

MitigationEnable authentication on the storage bucket, implement row-level security policies to restrict access to authorized users only, and configure least-privilege IAM policies to prevent unauthorized CRUD 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. Verify Capgo installation version
    Run the command to check the installed Capgo version (e.g., capgo --version, or check package.json, or query the Capgo API endpoint for version info) and compare it against the affected range: versions before 12.128.2 are vulnerable
    Affected if The installed version is below 12.128.2
  2. Inspect storage bucket accessibility
    Examine the cloud storage bucket configuration used by Capgo for app icons. Attempt an unauthenticated HTTP request to the bucket endpoint or review the bucket policy/ACL settings to determine if public access is allowed
    Affected if The bucket permits unauthenticated (anonymous) read, write, or delete operations without requiring credentials
  3. Confirm row-level security configuration
    Review the storage bucket settings or database policies to determine whether row-level security (RLS) or equivalent access control policies are enforced on the icon storage
    Affected if Row-level security controls are disabled or not configured for the icon storage
  4. Verify IAM policy restrictions
    Inspect the Identity and Access Management (IAM) policies attached to the storage bucket or the service account used by Capgo to determine if least-privilege principles are applied
    Affected if The IAM policies allow broad CRUD operations (read, write, delete) to the bucket without restrictive conditions or principal limitations

A Capgo installation is affected if it runs a version below 12.128.2 AND the associated cloud storage bucket for app icons is publicly accessible without authentication or lacks row-level security and restrictive IAM policies.

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

Enable authentication on the storage bucket, implement row-level security policies to restrict access to authorized users only, and configure least-privilege IAM policies to prevent unauthorized CRUD operations.

Recommended fix Moderate confidence

Capgo version 12.128.2 or later

  1. 1. Identify the Capgo installation in your environment
  2. 2. Check the current installed version of Capgo
  3. 3. If the version is before 12.128.2, upgrade to version 12.128.2 or later
  4. 4. After upgrading, verify that the images bucket now has proper row-level security controls enabled
  5. 5. Confirm that unauthenticated access to the images bucket is no longer possible
