CVE-2026-92787: Feast-Dev Feast

Critical severity, CVSS 9.8. EPSS: 0.7% chance of exploitation in the next 30 days.

Feast through 0.66.0 fails to verify JWT token signatures before establishing user identity, allowing attackers to bypass all role-based access control by presenting an unverified token with a hardcoded claim value. Attackers can obtain trusted internal identity and gain unchecked read and write access to all entities, feature views, data sources, and permission policies on the server.

Affected products

• Feast-Dev Feast: up to and including 0.66.0
