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 cause a denial of service due to uncontrolled resource consumption. Certain requests can cause internal processing to stall, which could make the service unavailable.

Questions about CVE-2026-17279
Is CVE-2026-17279 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?
Certain requests can stall the product's internal processing, which can make the service unavailable. This is a denial-of-service bug.Source: ibm.com, cve.org
