CVE-2026-41226Network attack vector

Unauthenticated redirection to attacker-chosen websites

Published Apr 30, 2026 · Updated Apr 30, 2026

Open redirect in Ricoh Web Image Monitor allows remote attackers to redirect users to arbitrary websites through crafted URLs. Ricoh and JPCERT/CC have not published the affected URL-processing locus or the operation that accepts an untrusted redirect destination. Exploitation requires a user to open the attacker-supplied URL; the resulting cross-site redirect can support phishing but does not directly alter the device.
