Deno.env.toObject() ignores the variables listed in --deny-env and returns all environment variables
Summary
Deno.env.toObject() ignores the variables listed in --deny-env and returns all environment variables
Original description
The description as published by the source.
Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to versions 2.1.13 and 2.2.13, the Deno.env.toObject method ignores any variables listed in the --deny-env option of the deno run command. When looking at the documentation of the --deny-env option this might lead to a false impression that variables listed in the option are impossible to read. Software relying on the combination of both flags to allow access to most environment variables except a few sensitive ones will be vulnerable to malicious code trying to steal secrets using the Deno.env.toObject() method. Versions 2.1.13 and 2.2.13 contains a patch.
