Associated Vulnerability

Title:Mockoon has a Path Traversal and LFI in the static file serving endpoint (CVE-2025-59049)
Description:Mockoon provides way to design and run mock APIs. Prior to version 9.2.0, a mock API configuration for static file serving follows the same approach presented in the documentation page, where the server filename is generated via templating features from user input is vulnerable to Path Traversal and LFI, allowing an attacker to get any file in the mock server filesystem. The issue may be particularly relevant in cloud hosted server instances. Version 9.2.0 fixes the issue.

Description

Mockoon before 9.2.0 contains a path traversal and local file inclusion caused by unsafe templating of server filenames from user input, letting attackers read arbitrary files on the mock server filesystem, exploit requires crafted request.
