What is CVE-2023-33966?

The Deno runtime for JavaScript and TypeScript has a vulnerability allowing outbound HTTP requests via built-in modules (node:http and node:https) without proper checks against the network permission allow list (--allow-net). This oversight can expose dependencies that rely on these modules to potential security threats. Users on Deno versions 1.34.0 and deno_runtime 0.114.0 should update to patched versions (Deno v1.34.1 and deno_runtime 0.114.1) to mitigate this issue, as no workarounds are available.

Affected Version(s)

deno deno = 1.34.0 = deno 1.34.0

deno deno_runtime = 0.114.0 = deno_runtime 0.114.0
