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.

Detection & mitigation playbook

Vendor / appliance

  1. Detect

    Inventory every ibm api connect deployment and check each version against the affected-products list above.

  2. Remediation status

    The records we use list no fixed version for CVE-2026-17188. Check the ibm api connect advisory for a patched release, and apply the workarounds below until you can upgrade.

  3. Mitigate without a patch

    Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
