CVE-2026-17344

Summary

IBM API Connect contains a server-side request forgery (SSRF) vulnerability in an unauthenticated service, allowing remote attackers to force the server to make unintended internal or external HTTP requests and potentially leak sensitive internal data.

Exploitability

Exploitation is straightforward for remote attackers since the vulnerable service is reachable without authentication and requires only crafting a malicious request to redirect internal requests.

Blast radius

Successful exploitation could expose internal services, credentials, or metadata via SSRF-induced requests, compromise data integrity through unintended writes, and enable further lateral movement within the network.

Detection

Defenders should monitor logs for unexpected outbound HTTP requests from the API Connect gateway to internal IP ranges (e.g., 10.x.x.x, 192.168.x.x, 172.16–31.x.x), localhost endpoints (127.0.0.1), or metadata services (169.254.169.254); anomalies in request destination patterns or timing may indicate SSRF activity.

Prioritized remediation

Upgrade to IBM API Connect 12.1.1.3 or later, as this version contains the fix for CVE-2026-17344.
