Summary
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 execute arbitrary code and access sensitive information from other tenants due to insufficient input validation. Uploaded custom module content is not sufficiently validated before it is processed, which could allow code to run with access beyond the user's own tenant.

Questions about CVE-2026-17150
Is CVE-2026-17150 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?
Uploaded custom module content is not sufficiently validated before it is processed. According to the checked facts, this can allow arbitrary code execution and access to sensitive information from other tenants.Source: ibm.com, cve.org
Which versions are affected by CVE-2026-17150?
API Connect: from 12.1.0.0 through 12.1.1.2; from 10.0.8.0 through 10.0.8.12.Source: cve.now feed data
Am I affected, and how do I check?
The listed ranges are IBM API Connect 12.1.0.0 through 12.1.1.2 and 10.0.8.0 through 10.0.8.12. The issue involves uploaded custom module content, so check the installed API Connect version against these ranges and whether custom modules are uploaded.Source: ibm.com, cve.org
