Summary
Arista CloudVision Portal is affected from 2026.2.0, from 2026.1.0 through 2026.1.2, from 2025.3.0 through 2025.3.3, and from 2020.3.0 before 2025.3.0. Insufficient validation of OIDC SSO provider configuration lets a user with high privileges direct server requests to arbitrary destinations (CWE-918). A remote user with high privileges can exploit this without user interaction.
