CVE-2026-17330

Summary

IBM API Connect versions 12.1.0.0 through 12.1.1.2 contain a server-side request forgery (SSRF) vulnerability (CWE-918) that allows an authenticated attacker to force the application to make unintended requests to internal or external systems, potentially exposing sensitive internal data or services.

Exploitability

Exploitation requires valid authentication credentials and the ability to submit crafted requests to vulnerable endpoints; no public exploit code is available, but the low attack complexity makes it feasible for skilled attackers.

Blast radius

Successful exploitation could lead to unauthorized access to internal network resources, cloud metadata services, or sensitive backend systems accessible to the API Connect server, with high confidentiality impact and some integrity risk.

Detection

Defenders should monitor for anomalous outbound HTTP/HTTPS requests from the API Connect server to internal IP ranges (e.g., 10.x.x.x, 192.168.x.x, 172.16.x.x–172.31.x.x), localhost (127.0.0.1), or cloud metadata endpoints (e.g., 169.254.169.254) in firewall or proxy logs, especially when originating from authenticated user sessions with unusual request patterns.

Prioritized remediation

Upgrade to IBM API Connect 12.1.1.3 or later, as this version includes fixes for CVE-2026-17330.
