CVE-2026-29059: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in windmill-labs windmill
Windmill is an open-source developer platform for internal code: APIs, background jobs, workflows and UIs. Prior to version 1.603.3, an unauthenticated path traversal vulnerability exists in Windmill's get_log_file endpoint "(/api/w/{workspace}/jobs_u/get_log_file/{filename})". The filename parameter is concatenated into a file path without sanitization, allowing an attacker to read arbitrary files on the server using ../ sequences. This issue has been patched in version 1.603.3.
AI Analysis
Technical Summary
Windmill-labs windmill before version 1.603.3 contains an unauthenticated path traversal vulnerability in the /api/w/{workspace}/jobs_u/get_log_file/{filename} endpoint. The filename parameter is concatenated directly into a file path without proper sanitization or validation, enabling attackers to traverse directories and read arbitrary files on the server. This vulnerability is identified as CWE-22 and has been assigned CVE-2026-29059. The vulnerability was publicly disclosed and patched in version 1.603.3.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to read arbitrary files on the server hosting the windmill application. This could lead to disclosure of sensitive information stored on the server. There is no indication of remote code execution or privilege escalation from the provided data. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade windmill to version 1.603.3 or later, where this path traversal vulnerability has been patched. No other mitigation actions are specified or required according to the available information.
