Summary
Impact A security issue has been identified in Chef 360 that could allow unauthorized access to protected API endpoints under specific conditions. This issue is due to improper handling of URL-encoded paths during request processing. In certain scenarios, an authenticated request may bypass standard access controls gaining additional privileges, potentially allowing access to API endpoints that are intended to be restricted to higher-permissioned roles. The impact is limited to environments where the affected request patterns can be triggered and depends on specific deployment configuration and access controls in place. Resolution The issue has been addressed through product updates that improve request validation and enforce strict path normalization before authorization checks. Customers are advised to update to the latest available version containing the fix, version 1.7.1 or later.
