Details
A vulnerability classified as critical was found in static-web-server Static Web Server up to 2.40.0. This vulnerability affects an unknown code. The manipulation with an unknown input leads to a symlink vulnerability. The CWE definition for the vulnerability is CWE-61.

This could allow an attacker to cause the product to operate on unauthorized files. As an impact it is known to affect confidentiality. CVE summarizes:
Static Web Server (SWS) is a production-ready web server suitable for static web files or assets. Versions 2.40.0 and below contain symbolic links (symlinks) which can be used to access files or directories outside the intended web root folder. SWS generally does not prevent symlinks from escaping the web server’s root directory. Therefore, if a malicious actor gains access to the web server’s root directory, they could create symlinks to access other files outside the designated web root folder either by URL or via the directory listing. This issue is fixed in version 2.40.1.
The advisory is available at github.com. This vulnerability was named CVE-2025-67487 since 12/08/2025. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but an exploit is available.
It is declared as proof-of-concept.
Upgrading to version 2.40.1 eliminates this vulnerability.
