CVE-2025-48888
Good to know:
Date: June 4, 2025
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.
