DescriptionCVE.org

The Deno Standard Library provides APIs for Deno and the Web. Prior to version 1.0.11, http/file-server's serveDir with showDirListing: true option is vulnerable to cross-site scripting when the attacker is a user who can control file names in the source directory on systems with POSIX file names.
