IBM API Connect Default Credentials Vulnerability
First seen Jul 11, 2026 · Updated Jul 11, 2026 · CVSS 8.1
IBM API Connect versions 12.1.0.0 through 12.1.0.3 ship with default credentials that remain active until an administrator manually enforces a password change. Attackers aware of these default credentials can gain unauthorized access to the API management platform before remediation occurs, potentially compromising API gateways, backend integrations, and associated secrets.
Technical Analysis
CVE-2026-3144 (CVSS 8.1) stems from IBM API Connect's failure to force credential rotation on initial deployment, leaving well-known default username/password pairs valid and exploitable by any attacker with network access to the management interface. Exploitation requires no advanced technique beyond credential-stuffing with published default values, making this a low-complexity, high-impact attack vector typically classified as CWE-1392 (Use of Default Credentials). Successful access grants control over API definitions, gateway policies, and potentially backend service credentials managed through the platform. Organizations that use API Connect as the gateway or management layer for AI agent tool-calling, RAG data retrieval, or LLM API orchestration are at risk of attackers intercepting, modifying, or exfiltrating API keys and traffic that agents rely on, enabling downstream prompt injection, data exfiltration, or man-in-the-middle manipulation of agent-to-tool communications.
Affected Systems
IBM API Connect versions 12.1.0.0, 12.1.0.1, 12.1.0.2, and 12.1.0.3 prior to enforced credential update; deployments where default administrative or service account credentials have not been manually rotated post-installation.
Indicators of Compromise
- No specific IOCs published; indicators would include unauthorized login events using default account names on API Connect management consoles, unexpected API Connect configuration changes, and anomalous access logs from unrecognized source IPs against the management interface.
Remediation Steps
- 1
Apply IBM Security Patch
Upgrade to the IBM-provided fixed release of API Connect that enforces mandatory credential change on first login.
- 2
Rotate Default Credentials Immediately
Manually change all default administrative and service account passwords across every API Connect instance, regardless of patch status.
- 3
Restrict Management Interface Access
Limit network access to the API Connect management console to trusted internal networks or VPN, and enforce MFA where supported.
- 4
Audit Access Logs
Review authentication logs for use of known default account names to detect prior unauthorized access.
- 5
Rotate Downstream API Keys and Secrets
If the platform manages credentials used by AI agents or backend integrations, rotate those keys and secrets as a precaution against exposure.
