Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. Insufficient validation of parameters in

Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. Insufficient validation of parameters in Deno.makeTemp* APIs would allow for creation of files outside of the allowed directories. This may allow the user to overwrite important files on the system that may affect other systems.

A user may provide a prefix or suffix to a Deno.makeTemp* API containing path traversal characters. This is fixed in Deno 1.41.1.
