The short answer

CVE-2026-17290 affects IBM API Connect and is rated high (CVSS 8.5). It is not in CISA's KEV catalog; EPSS puts the chance of exploitation in the next 30 days at 0.35%. The vendor has linked a patch.

What it is

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.

Weakness: CWE-290.
