Sandbox Breakout / Arbitrary Code Execution in safer-eval
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | safer-eval | < 1.3.4 | 1.3.4 |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
