CVE-2026-16695
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk5th percentile - higher than 5% of all known CVEs
Summary
IBM i Access Client Solutions versions 1.1.2.0 through 1.1.9.13 could allow a local attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.
Risk Assessment
A local attacker could gain the ability to execute arbitrary code in the user's context, potentially leading to full system compromise.
Recommendation
Update IBM i Access Client Solutions to a patched version and restrict access to the application to trusted users only.
