Open redirect vulnerability exists in Multiple laser printers and MFPs which implement Ricoh Web Image Monitor. When accessing a specially crafted URL, the user may be redirected to an arbitrary website. As a result, the user may become a victim of a phishing attack.

Security readout for executives and security teams

Plain-English summary

Affected Ricoh and Konica Minolta printers or multifunction devices can redirect users from a trusted device-management address to an attacker-chosen website. A convincing link could therefore support phishing. The issue does not directly compromise the printer according to the supplied evidence, but exposed management interfaces may increase organizational risk.

Executive priority

Treat this as a normal-priority phishing-risk remediation, prioritizing externally or broadly reachable management interfaces. Request a model-level inventory and vendor-advisory comparison. Escalate if affected interfaces are internet-accessible, heavily used, or associated with observed phishing activity.

Technical view

CVE-2026-41226 is a CWE-601 open redirect in Ricoh Web Image Monitor implementations. It is network-accessible, requires no privileges, has low attack complexity, and requires user interaction. The supplied CVSS 4.0 score is 5.1. Vendor advisories must be consulted because affected models and firmware versions are not specified in the bundle.

Likely exposure

Exposure is most likely where affected Web Image Monitor interfaces are reachable and users can be persuaded to open crafted links. Exact affected models and versions require vendor confirmation. Devices whose management interfaces are tightly restricted may present less opportunity, but the source bundle does not establish complete mitigating conditions.

Exploitation context

The source bundle describes phishing through arbitrary redirection. It provides no evidence of active exploitation, and the CVE is not identified as being in KEV. No public exploit availability is established by the supplied sources.

Researcher notes

The record identifies multiple products but delegates precise version scope to vendor information. CVSS 4.0 indicates no direct vulnerable-system confidentiality, integrity, or availability impact, with low subsequent-system integrity impact. Validation should remain controlled and non-destructive. Patch availability and fixed firmware versions cannot be confirmed from the supplied bundle alone.

Mitigation direction

  • Identify printers and MFPs running Ricoh Web Image Monitor.
  • Compare every model and firmware version with the applicable vendor advisory.
  • Apply vendor-provided updates or remediation when listed for the device.
  • Restrict management-interface access to trusted administrative networks where operationally feasible.
  • Warn users against unexpected printer-management links pending remediation.

Validation and detection

  • Inventory Web Image Monitor devices, including Ricoh and Konica Minolta models.
  • Record each device model, firmware version, and management-interface exposure.
  • Confirm remediation status against the current applicable vendor advisory.
  • In a controlled environment, verify untrusted redirect destinations are rejected.
  • Review relevant web or proxy logs for suspicious device-linked redirects.
