Sandbox Breakout / Arbitrary Code Execution in safer-eval
Quick fix
GHSA-r3x4-wr4h-pw33 — safer-eval: upgrade to the fixed version with the command below.
npm install safer-eval@1.3.4Details
Versions of `safer-eval` prior to 1.3.4 are vulnerable to Sandbox Escape leading to Remote Code Execution. A payload using constructor properties can escape the sandbox and execute arbitrary code. For example, evaluating he string `console.constructor.constructor('return process')().env` prints `process.env` to the console.
## Recommendation
Upgrade to version 1.3.4 or later.
