CVE-2026-8100
Received Received - Intake
Chef 360 API Access Control Bypass via URL Path Handling

Publication date: 2026-06-18

Last updated on: 2026-06-18

Assigner: Progress Software Corporation

Description
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.

Executive Summary

This vulnerability exists in Chef 360 and involves improper handling of URL-encoded paths during request processing.

Under certain conditions, an authenticated request can bypass standard access controls and gain additional privileges.

This may allow access to protected API endpoints that are normally restricted to users with higher permission levels.

The issue depends on specific deployment configurations and the ability to trigger affected request patterns.

Impact Analysis

If exploited, this vulnerability can allow an authenticated user to gain unauthorized access to protected API endpoints.

This unauthorized access could lead to privilege escalation, exposing sensitive operations or data intended only for higher-permission roles.

The impact is limited to environments where the specific request patterns can be triggered and depends on the deployment's access controls.

Mitigation Strategies

To mitigate this vulnerability, customers are advised to update to the latest available version of Chef 360 containing the fix, which is version 1.7.1 or later.

The update improves request validation and enforces strict path normalization before authorization checks, preventing unauthorized access to protected API endpoints.
