Description

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 attacker to perform an account takeover due to an open redirect vulnerability. The redirect address used during sign-in is not sufficiently validated, which could allow authentication results to be sent to an attacker-controlled location.

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-2026-17297. Check the ibm api connect advisory for a patched release, and apply the workarounds below until you can upgrade.

  3. Mitigate without a patch

    Stop reflecting attacker-controlled destinations: resolve every redirect target against an allowlist of paths or hosts you own, prefer a server-side key over a full URL in the request, and reject absolute URLs entirely where the flow only ever needs a relative one. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
