CVE-2026-3144
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 · uneditedIBM API Connect 12.1.0.0 through 12.1.0.3 uses default credentials which could allow an attacker to gain unauthorized access to the application before the system enforces a credential update.
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 confidenceIBM API Connect versions 12.1.0.0 through 12.1.0.3 ship with default credentials that remain active until the system forces a password update. An attacker with knowledge of these default credentials can authenticate with administrative privileges before the credential rotation is enforced, potentially gaining full unauthorized access to the API management platform.

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 installed IBM API Connect versionRun the version check command for IBM API Connect (typically via 'apic status' or check the product dashboard for the version number)Affected if The installed version is 12.1.0.0, 12.1.0.1, 12.1.0.2, or 12.1.0.3 (any version >= 12.1.0.0 and < 12.1.1.0)
-
Verify default credentials have been changedAttempt to authenticate using the known default administrative username and compare against the initial default password that ships with the product, then confirm the password has been modifiedAffected if Default credentials remain unchanged or still authenticate successfully, indicating the password rotation has not been enforced yet
-
Confirm password rotation policy statusCheck the security or authentication policy configuration in the API Connect admin console or configuration files to determine if forced password change on first login is enabledAffected if Password rotation policy is not enforced or shows as disabled, meaning default credentials remain active
-
Review administrative access logsInspect IBM API Connect access and audit logs for administrative login events, particularly from unexpected IP addresses or at unusual times, before the initial password change was completedAffected if There are unauthorized administrative login attempts or successful admin access events that occurred prior to documented credential rotation
A user is affected if their IBM API Connect installation is version 12.1.0.0 through 12.1.0.3 AND default credentials have not been changed or password rotation has not been enforced yet.

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 · scoped12.1.1.0
Immediately change all default credentials on affected IBM API Connect installations before initial deployment or if already deployed. Audit access logs for unauthorized administrative access and enforce credential complexity requirements.
12.1.1.0 or later
- Schedule a maintenance window for the IBM API Connect upgrade
- Back up the current IBM API Connect configuration, data, and all critical assets
- Obtain IBM API Connect version 12.1.1.0 or later from IBM Fix Central or IBM Passport Advantage
- Follow IBM's official upgrade documentation to upgrade from 12.1.0.x to 12.1.1.0 or later
- After successful upgrade, immediately change all default credentials to strong, unique passwords per IBM API Connect security best practices
- Verify the upgrade completed successfully and the default credentials vulnerability is resolved
- Review audit and access logs for any unauthorized access attempts that may have occurred before the upgrade
