CVE-2025-48888 Information

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.
