Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.8.0 and prior to version 1.40.4, Deno improperly checks that an import specifierโ€™s hostname is equal to or a child of a tokenโ€™s hostname, which can cause tokens to be sent to servers they shouldnโ€™t be sent to. An auth token intended for example[.]com may be sent to notexample[.]com. Anyone who uses DENO_AUTH_TOKENS and imports potentially untrusted code is affected. Version 1.40.0 contains a patch for this issue
