Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
buffer-expand
Advanced tools
Expand a buffer to a specified length. If the buffer is smaller than the specified length, the remaining space is filled with random bytes. A 32-bit Unsigned Big-Endian Integer containing the length of the data is always prepended to the buffer.
npm install buffer-expand
const size = 25
const { expand, shrink } = require('buffer-expand')(size)
const data = Buffer.from('Hello World!')
const newData = expand(data)
console.log(data, newData)
// Prints:
// <Buffer 48 65 6c 6c 6f 20 57 6f 72 6c 64 21>
// <Buffer 00 00 00 0c 48 65 6c 6c 6f 20 57 6f 72 6c 64 21 91 5c d3 2f>
assert(newData.length === size)
assert(shrink(newData).equals(data))
