CVE-2026-8100: CWE-23 Relative path traversal in Progress Chef Chef360
CVE-2026-8100 is a high-severity vulnerability in Progress Chef Chef360 involving a relative path traversal (CWE-23). It allows an authenticated user to bypass access controls via improper handling of URL-encoded paths, potentially gaining unauthorized access to protected API endpoints. The issue depends on specific deployment configurations and request patterns. The vendor has released a fix in version 1.7.1 or later to address this by improving request validation and enforcing strict path normalization before authorization checks.
AI Analysis
Technical Summary
This vulnerability in Chef360 arises from improper handling of URL-encoded paths during request processing, enabling an authenticated user with limited privileges to bypass standard access controls. This can result in unauthorized access to API endpoints restricted to higher-permission roles. The impact is environment-dependent, relying on the ability to trigger affected request patterns and existing access control configurations. The vendor fixed the issue by enhancing request validation and enforcing strict path normalization prior to authorization checks in version 1.7.1 and later.
Potential Impact
An authenticated user with limited privileges may exploit this vulnerability to gain unauthorized access to protected API endpoints intended for higher-privileged roles. This could lead to unauthorized information disclosure or actions within the Chef360 environment. The impact is limited to environments where the specific request patterns can be triggered and depends on deployment and access control configurations.
Mitigation Recommendations
A fix is available in Chef360 version 1.7.1 and later. Customers are advised to update to these versions to remediate the vulnerability. No additional mitigation steps are indicated beyond applying the official update.
