    CVE-2025-48934 – Deno Deny Env Variable Information Disclosure

    June 4, 2025

    CVE ID : CVE-2025-48934

    Published : June 4, 2025, 8:15 p.m. | 3 hours, 22 minutes ago

    Description : 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.

    Severity: 0.0 | NA
