CVE-2026-101152: Arista CloudVision Portal SSO credential redirection

CVE-2026-101152 · Severity: high · CVSS 8 · Published 2026-10-06

Arista CloudVision Portal is a network management and visibility platform. An authentication flaw in its Single Sign-On (SSO) login process allows an attacker to craft a malicious link that, when clicked by a user, redirects authentication credentials from the user's identity provider to an attacker-controlled server instead of CloudVision. An attacker who obtains these credentials gains immediate access to the user's CloudVision account and the network infrastructure it manages.

Technical details

CVE-2026-101152 is an open redirect vulnerability (CWE-601) in CloudVision's SSO authentication flow that fails to validate redirect URLs. An unauthenticated attacker can craft a specially formed request that causes the external identity provider (OIDC or SAML) to transmit authentication tokens to an attacker-controlled URL. This requires user interaction (clicking a malicious link) and the target to have SSO configured; credentials in hand allow account takeover.
