CVE-2026-56305
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 password change endpoint that allows attackers to change user passwords without requiring current password confirmation. Attackers with temporary session access can exploit this flaw to permanently lock out legitimate users and achieve full account takeover.
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 version 12.128.2 has an authentication bypass vulnerability in its password change endpoint that fails to validate the user's current password before allowing a new password to be set. Attackers who obtain temporary session access (e.g., through session hijacking or expired tokens) can exploit this flaw to change any user's password without knowledge of their current credentials, achieving full account takeover.

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 versionLocate the installed Capgo package or application and retrieve its version number. Common methods include: checking package.json, looking for version in the application settings UI, or querying the API endpoint /api/version if available.Affected if The installed version is below 12.128.2
-
Verify password change endpoint existsDetermine if the password change functionality is exposed in the application. This may be accessible via the user settings page, API endpoint such as /api/auth/password or /api/users/:id/password, or administrative panel.Affected if The password change endpoint is present and accessible to users
-
Test current password validationAttempt to change a user's password without providing the current password. This requires either access to the application as a user or interception of the password change request to observe whether the current password field is validated server-side.Affected if The endpoint accepts a password change request without requiring the user's current password as validation
You are affected if Capgo version is below 12.128.2 AND the password change endpoint is accessible without requiring current password verification.

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 Capgo to version 12.128.2 or later, which includes proper current password verification in the password change endpoint. Additionally, implement rate limiting and session monitoring on sensitive endpoints to mitigate abuse of temporary session access.
Capgo version 12.128.2 or later
- 1. Identify the current installed version of Capgo in your environment
- 2. Upgrade Capgo to version 12.128.2 or later to resolve the authentication bypass vulnerability
- 3. After upgrading, verify that the password change endpoint now correctly requires current password confirmation
- 4. Review access logs for any suspicious password change requests that occurred before the upgrade
- 5. Consider forcing password resets for high-risk or privileged accounts as a precautionary measure
