CVE-2024-27933 is a vulnerability in Deno, a JavaScript, TypeScript, and WebAssembly runtime. In version 1.39.0, the use of raw file descriptors in the op_node_ipc_pipe() function results in the premature closing of arbitrary file descriptors. This can allow an attacker to bypass permission prompts by reopening the standard input as a different resource. The vulnerability can be exploited by an attacker controlling the code executed within a Deno runtime to achieve arbitrary code execution on the host machine, regardless of permissions. The base severity of this vulnerability is rated as HIGH, with a CVSS score of 8.2, indicating its potential danger to organizations. A patch or update to Deno version 1.39.1 or higher should be applied to remediate this vulnerability and mitigate its impact.
