CVE-2026-8100: CWE-23 Relative path traversal in Progress Chef Chef360
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.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-8100) in Progress Chef Chef360 arises from improper normalization of URL-encoded paths, leading to a relative path traversal (CWE-23). Under certain conditions, an authenticated user can bypass standard access controls and access API endpoints restricted to higher privilege roles. The vulnerability is limited to environments where the specific request patterns can be triggered and depends on deployment-specific access controls. The vendor addressed the issue by improving request validation and enforcing strict path normalization before authorization checks. The fix is included in Chef360 version 1.7.1 and later.
Potential Impact
An authenticated user with lower privileges may exploit this vulnerability to gain unauthorized access to protected API endpoints that should be restricted to higher-permission roles. This could lead to unauthorized information disclosure or actions within the affected system. The impact is environment-dependent and requires the ability to trigger the vulnerable request patterns.
Mitigation Recommendations
A fix is available in Progress Chef Chef360 version 1.7.1 and later. Customers should update to version 1.7.1 or newer to remediate this vulnerability. No additional mitigation steps are indicated beyond applying the official update.
