0 CVE-2026-21409 is an authorization bypass vulnerability in Ricoh Streamline NX versions 3.5.1 through 24R3. The flaw allows a man-in-the-middle attacker to intercept communications and craft requests that can retrieve user registration information and OpenID Connect (OIDC) tokens. This vulnerability does not require user interaction or authentication but does require the attacker to be positioned to intercept network traffic. The CVSS score is 5.9 (medium severity) due to the high impact on confidentiality but no impact on integrity or availability. Exploitation could lead to unauthorized access to sensitive user identity tokens, potentially enabling further impersonation or access escalation. No known exploits are currently reported in the wild. European organizations using affected Ricoh Streamline NX versions are at risk, especially those with sensitive document workflows relying on OIDC authentication.
