Moderate severityNVD Advisory· Published Jun 4, 2025· Updated Jun 4, 2025
Deno run with --allow-read and --deny-read flags results in allowed
CVE-2025-48888
Description
Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.41.3 and prior to versions 2.1.13, 2.2.13, and 2.3.2, deno run --allow-read --deny-read main.ts results in allowed, even though 'deny' should be stronger. The result is the same with all global unary permissions given as --allow-* --deny-*. This only affects a nonsensical combination of flags, so there shouldn't be a real impact on the userbase. Users may upgrade to version 2.1.13, 2.2.13, or 2.3.2 to receive a patch.
