CVE-2026-31982: Nozominetworks Cmc

High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

An Open Redirect vulnerability was discovered in the SAML Single Sign-On functionality due to insufficient validation of a user-controlled redirection parameter. An unauthenticated attacker can craft a request to the SAML sign-in endpoint and poison the cached SAML redirection for other users who subsequently initiate SAML Single Sign-On, enabling phishing and credential-theft attacks, as well as disrupting SAML authentication for all affected users.

Affected products

• Nozominetworks Cmc: before 26.2.0 (fixed in 26.2.0)
• Nozominetworks Guardian: before 26.2.0 (fixed in 26.2.0)
