High CVSS 8.3
CVE-2026-18235
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary Control Language commands due to insufficient input validation.
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and degrade the service.
- Weakness
- Unfiltered input reaches the system shell, letting the attacker run their own commands on the server.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
