High CVSS 8.8
CVE-2026-18847
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote unauthenticated attacker to harvest credentials due to spoofing of Navigator for i.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- A request’s origin is not validated, letting a third-party site act on the user’s behalf.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
