CVE-2026-17399: Multiple Vulnerabilities in IBM API Connect

Q: Is unauthenticated internet access alone sufficient to exploit this issue?

No. The issue requires a remote attacker to be authenticated before they can upload content that is processed by the server.

Q: Are releases outside the listed version ranges confirmed to be affected?

The provided information identifies affected releases only in the 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 ranges. It does not establish whether releases outside those ranges are affected or unaffected.

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 due to insufficient validation of uploaded content. Content uploaded to the product is not sufficiently checked before it is processed, which could allow code to run on the server.
