Summary

CVE-2024-32477 is a vulnerability affecting Deno, a JavaScript, TypeScript, and WebAssembly runtime. By using ANSI escape sequences and exploiting a race condition between `tcflush(0, TCIFLUSH)` and reading standard input, an attacker can manipulate Deno's permission prompt and force it to allow an unsafe action, bypassing the user input. ANSI escape sequences act as information requests to the master terminal emulator, and the terminal emulator sends back the reply in the PTY channel, which Deno uses for standard I/O. This vulnerability was fixed in Deno version 1.42.2.
