tag_summary = "Mongoose is prone to a remote file-disclosure vulnerability because it
fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to view the source code
of files in the context of the server process, which may aid in
further attacks.

This issue affects Mongoose 2.8; other versions may be
vulnerable as well.";
