Exploitability
| CWE ID | Description |
|---|---|
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-3188 is a path traversal vulnerability in the feiyuchuixue sz-boot-parent project up to version 1.3.2-beta. It affects the API endpoint /api/admin/common/download/templates, where the templateName parameter is used to build a file path without proper validation. This allows an attacker to manipulate the templateName argument with directory traversal sequences like ../ to access files outside the intended templates directory.
Because of this flaw, an attacker can remotely read arbitrary resource files on the server, potentially exposing sensitive information. The vulnerability can be exploited without authentication, and a public exploit is available.
How can this vulnerability impact me? :
This vulnerability can impact you by allowing unauthorized remote attackers to read arbitrary files on the server hosting the vulnerable application. This can lead to exposure of sensitive or confidential information stored on the server.
Since the exploit is easy to execute and publicly available, it increases the risk of data leakage or information disclosure, which can compromise the confidentiality of your system.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': 'This vulnerability can be detected by testing the API endpoint /api/admin/common/download/templates for path traversal attempts by manipulating the templateName parameter.'}, {'type': 'paragraph', 'content': 'A common detection method is to send crafted HTTP requests with directory traversal sequences such as ../ in the templateName parameter to see if files outside the intended directory can be accessed.'}, {'type': 'list_item', 'content': 'Example curl command to test for path traversal:'}, {'type': 'list_item', 'content': 'curl -v "http://<target-host>/api/admin/common/download/templates?templateName=../../../../etc/passwd"'}, {'type': 'list_item', 'content': 'If the response contains contents of sensitive files (e.g., /etc/passwd), the vulnerability is present.'}] [1, 2]
What immediate steps should I take to mitigate this vulnerability?
The recommended immediate mitigation is to upgrade the affected component feiyuchuixue sz-boot-parent to version 1.3.3-beta or later, which includes a patch that implements path validity checks on the template download interface.
Until the upgrade can be applied, consider restricting access to the vulnerable API endpoint and monitoring for suspicious requests containing directory traversal patterns.
