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-2026-30351 is a path traversal vulnerability found in the UI/static component of the leonvanzyl autocoder project. This vulnerability allows remote attackers to read arbitrary files on the server by sending specially crafted URL paths containing traversal sequences such as "../". Essentially, the affected component improperly handles file paths, enabling attackers to access files outside the intended directory.
How can this vulnerability impact me? :
The primary impact of this vulnerability is information disclosure. Attackers can exploit it to read arbitrary files on the server with the same permissions as the server's operating system user. This could lead to exposure of sensitive data stored on the server, potentially including configuration files, credentials, or other private information.
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for HTTP requests containing path traversal sequences such as "../" in the URL paths targeting the UI/static component of the leonvanzyl autocoder application.
You can use network traffic inspection tools or web server logs to identify suspicious requests attempting to access arbitrary files via crafted URLs.
Example commands to detect such attempts include:
- Using grep on web server access logs to find traversal attempts: grep -E '\.\./' /path/to/access.log
- Using tcpdump or tshark to capture HTTP traffic and filter for traversal sequences in URLs.
- Using curl or wget to test the server by sending crafted URLs containing traversal sequences and observing the response.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting or disabling access to the vulnerable UI/static component until a patch is applied.
Implement input validation and sanitization on URL paths to prevent traversal sequences from being processed.
Apply any available patches or updates from the vendor or project repository that address this vulnerability.
Use web application firewalls (WAF) or intrusion detection systems (IDS) to block or alert on requests containing path traversal patterns.
Limit file system permissions of the server process to minimize the impact of any successful traversal attempts.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
CVE-2026-30351 is a path traversal vulnerability that allows attackers to read arbitrary files on the server, leading to information disclosure.
Such unauthorized access to sensitive files could potentially lead to violations of data protection regulations like GDPR or HIPAA if personal or protected health information is exposed.
However, the provided context and resources do not explicitly discuss the impact of this vulnerability on compliance with these or other common standards and regulations.
