High CVSS 7.1
CVE-2026-18509
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to gain privilege escalation via the Navigator for i debugger. This could allow the attacker to access or manipulate sensitive data on the system, or create new profiles with elevated privileges on the IBM i system.
What this means
- Exposure
- Exploitable with local access to the machine, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can read sensitive data and modify or destroy data.
- Weakness
- Authorisation is not checked in the right place, so a user acts outside their scope.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
