Publication date: 2026-08-31

Last updated on: 2026-08-31

Assigner: GitHub, Inc.

Description
Goploy is an open-source automation deployment system. Prior to version 1.18.0, a severe path traversal vulnerability exists in its backend API endpoints, specifically /deploy/fileDiff (File Compare), when handling file paths provided by the client. This issue has been patched in version 1.18.0.

CWE-200 The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
CWE-22 The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Executive Summary

CVE-2026-53553 is a path traversal vulnerability in Goploy, an open-source automation deployment system. It affects versions 1.17.5 and earlier and exists in the /deploy/fileDiff endpoint. The flaw allows attackers to use directory traversal sequences like ../ to access files outside the intended project scope on both the local host and managed remote servers.

Detection Guidance

To detect this vulnerability, monitor network traffic for POST requests to /deploy/fileDiff with filePath parameters containing traversal sequences like ../ or ..\. Check Goploy logs for suspicious file access attempts outside project directories. Use tools like curl to test endpoints with crafted payloads such as ../../../../../../../../../../etc/passwd.

Impact Analysis

This vulnerability can allow attackers to read sensitive files such as system passwords, SSH private keys, configuration files, and database credentials. It may also enable remote code execution or lateral movement across networks. Attackers only need low privileges and basic system setup to exploit it.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive files, including configuration files, database credentials, or system passwords. For GDPR, this may result in unauthorized data access or breaches, requiring notification under Articles 33-34. For HIPAA, exposure of protected health information (PHI) could violate the Security Rule, leading to penalties or corrective action plans.

Mitigation Strategies

Immediately upgrade Goploy to version 1.18.0 or later. If upgrading is not possible, restrict access to the /deploy/fileDiff endpoint and remove the File Compare permission from low-privilege users. Implement strict input validation for filePath parameters to block traversal sequences and absolute paths.
