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.

GHSA-xqxc-x6p3-w683Deno run with --allow-read and --deny-read flags results in allowed2025-06-04ghsa · osvUS
### Summary `deno run --allow-read --deny-read main.ts` results in allowed, even though 'deny' should be stronger. Same with all global unary permissions given as `--allow-* --deny-*`. ### Details Caused by the fast exit logic in #22894. ### PoC Run the above command expecting no permissions to be passed. ### Impact This only affects a nonsensical combination of flags, so there shouldn't be a real impact on the userbase.
