Advisories for Npm/Socket.io-File package

The socket.io-file package for Node.js relies on client-side validation of file types, which allows remote attackers to execute arbitrary code by uploading an executable file via a modified JSON name field. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

A Path Traversal issue was discovered in the socket.io-file package for Node.js. The socket.io-file::createFile message uses path.join with ../ in the name option, and the uploadDir and rename options determine the path.
