How to fix?

Upgrade deno to version 1.44.1 or higher.

Overview

deno is an a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.

Affected versions of this package are vulnerable to Exposure of Sensitive Information to an Unauthorized Actor through the .npmrc support process. An attacker can intercept and misuse authentication tokens by exploiting the credential transmission to unintended domains.

Note: All users relying on .npmrc are potentially affected by this vulnerability if their private registry references tarball URLs at a different domain. This includes usage of deno install subcommand, auto-install for npm: specifiers and LSP usage.

Workaround

If your private registry ever serves tarballs at a different domain, rotate your registry credentials.
