This security issue was assigned the identifier GHSA-qjfh-xc44-rm9x and is categorized under CWE-22 (GitHub Advisory).

The vulnerability stems from insufficient input sanitization in URLs when processing file requests. This implementation flaw allows attackers to use relative paths when fetching files, potentially exposing sensitive server files. The issue is classified as CWE-22 (Path Traversal) and has been assessed as having High severity (GitHub Advisory).

The vulnerability enables attackers to access files on the server by exploiting the path traversal weakness. This could potentially lead to unauthorized access to sensitive files outside the intended directory structure (GitHub Advisory).

The vulnerability affects all versions of the file-static-server package, with no patched versions available. The high severity rating suggests that exploitation is practical and could lead to significant security implications (GitHub Advisory).

Currently, no fix is available for this vulnerability. The recommended mitigation strategy is to consider using an alternative module until a security fix is made available (GitHub Advisory).
