Summary
IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information from internal network resources due to server-side request forgery. Destination checks on outbound requests can be bypassed, which could allow the server to reach internal systems that should be blocked.

Questions about CVE-2026-17355
Is CVE-2026-17355 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
Server-side request forgery makes the server send requests to internal systems that should be blocked, which can expose sensitive information from internal network resources.Source: ibm.com, cve.org
