CVE-2026-17290

EUVD-2026-118682
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.
