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 due to insufficient validation of uploaded content. Content uploaded to the product is not sufficiently checked before it is processed, which could allow code to run on the server.

Explain CVE-2026-17399 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-17399?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-17399?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-17399 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
