CVE-2026-17150: Multiple Vulnerabilities in IBM API Connect

Q: Which deployments are affected?

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

Q: What access does an attacker need to exploit this issue?

An attacker must be remotely authenticated and able to upload custom module content. The issue arises because that uploaded content is not sufficiently validated before processing.

Q: What could exploitation allow beyond the attacker’s own tenant?

Successful exploitation could allow arbitrary code execution and access to sensitive information belonging to other tenants. The processed custom module content may run with access beyond the authenticated user’s own tenant.

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 execute arbitrary code and access sensitive information from other tenants due to insufficient input validation. Uploaded custom module content is not sufficiently validated before it is processed, which could allow code to run with access beyond the user's own tenant.
