CVE-2026-17299: Multiple Vulnerabilities in IBM API Connect

Q: Which deployments are affected?

IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 are affected.

Q: What level of access does an attacker need?

Exploitation requires remote authenticated access to IBM API Connect and the ability to submit definitions that contain external references.

Q: What can an attacker obtain or reach through exploitation?

An attacker may cause API Connect to resolve unrestricted external references, enabling arbitrary file reads and server-side request forgery. Retrieved content could be returned to the attacker.

Updated

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to perform arbitrary file reads and server-side request forgery due to unrestricted resolution of external references. Externally referenced content in submitted definitions is not sufficiently restricted when processed, and the retrieved content could be returned to the attacker.
