[NEW] [high] IBM i: Multiple Vulnerabilities
An attacker can exploit multiple vulnerabilities in IBM i to execute arbitrary code, elevate privileges, conduct a SQL injection attack, conduct a denial of service attack, bypass security measures, and disclose information.
CSIRTS triage
- What
- Multiple vulnerabilities enable code execution, privilege escalation, SQL injection, denial-of-service, security bypass, and information disclosure.
- Who is affected
- Systems running IBM i across affected versions.
- Urgency
- High severity with diverse attack classes including RCE and SQL injection; prioritize patching immediately.
- Action
- Apply updates for all eight CVEs (CVE-2026-16722, CVE-2026-16860, CVE-2026-16863, CVE-2026-16907, CVE-2026-16908, CVE-2026-16961, CVE-2026-16967, CVE-2026-16975).

Exploitation outlook
EPSS (FIRST.org) estimates each CVE’s probability of exploitation in the next 30 days — here is the CSIRTS.com read on those numbers.
- Low exploitation riskCVE-2026-167220.28% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 20% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-168600.51% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 41% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-168630.34% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 27% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-169070.41% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 34% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-169080.40% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 34% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-169610.31% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 24% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-169670.25% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 17% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-169750.53% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 42% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-169870.11% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 2% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-170820.28% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 20% of all EPSS-scored CVEs.
