Privilege escalation via encoded path traversal
Published Jun 18, 2026 · Updated Jun 18, 2026
Authentication bypass in Progress Chef 360 Platform before 1.7.1 allows remote authenticated users to access protected API endpoints. The API gateway's NGINX request processing checks authorization on a URL-encoded path before strict normalization, so encoded traversal resolves to a route with higher permissions. Exploitation requires an authenticated account and a deployment in which the affected encoded request pattern reaches a role-restricted endpoint.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
