CVE-2024-27931 – Insufficient permission checking in `Deno.makeTemp*` APIs

https://notcve.org/view.php?id=CVE-2024-27931

05 Mar 2024 — 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. • https://github.com/denoland/deno/security/advisories/GHSA-hrqr-jv8w-v9jh • CWE-20: Improper Input Validation •
