Status: published. Published: 2026-11-07. Updated: 2026-11-11.

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 token to be accepted that should be rejected due to an improperly implemented security check. Under certain conditions, token validation is incomplete, so a token may be accepted for a purpose it was not intended for.

## Remediation
