Multiple Vulnerabilities in IBM API Connect

Published Nov 7, 2026 CVSS 3.1 · 8.5 High EPSS < 1% KEV · Not listed
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 authenticated attacker to create unauthorized user accounts due to improper verification of cryptographic signatures. Identity information from a login provider is accepted without its signature being fully verified, so forged identity data could be used to create accounts.
