A path traversal vulnerability has been identified in Florensia Widjaja BioinfoMCP versions up to 7ada7918b9e515604d3c0ae264d3a9af10bf6e54. The issue resides in the Upload function of the Upload Endpoint, specifically within the file bioinfo_mcp_platform/app.py. The vulnerability allows for arbitrary file writing by manipulating the 'filename' attribute of uploaded files, enabling attackers to overwrite files outside the intended directory. This issue can be exploited remotely, and the vulnerability has been publicly disclosed.
It is recommended to restrict the upload functionality to trusted users until the vulnerability is addressed. Additionally, directory separators and absolute path indicators should be removed from filenames before saving. Using server-generated names for uploaded files, while keeping the original name as metadata, can also mitigate the issue.
