Vulnerability from github – Published: 2026-02-03 17:42 – Updated: 2026-02-04 21:55

Summary

Compressing Vulnerable to Arbitrary File Write via Symlink Extraction

Details

Arbitrary File Write via Symlink Extraction in `github.com/node-modules/compressing`

Brief Introduction

The compressing npm package extracts TAR archives while restoring symbolic links without validating their targets. By embedding symlinks that resolve outside the intended extraction directory, an attacker can cause subsequent file entries to be written to arbitrary locations on the host file system.

Depending on the extractor’s handling of existing files, this behavior may allow overwriting sensitive files or creating new files in security-critical locations.

Affected Component and Versions

Component: github.com/node-modules/compressing
Affected Versions: <= 1.10.3 || =2.0.0

Vulnerability Details

Root Cause

compressing.tar.uncompress sanitizes the destination paths of archive entries, but it does not restrict or validate the targets of symlinks contained in TAR archives. During extraction, the library creates those symlinks inside the output directory. Later entries that resolve through the symlink are written to the symlink target rather than the intended extraction root, enabling an arbitrary file write.

Impact

An attacker who can supply a crafted TAR archive can:

Cause files to be written outside the intended extraction directory (arbitrary file write via symlink traversal).
Write files to attacker-controlled paths on the host file system once symbolic links are followed during extraction.
In environments where extraction is performed with elevated privileges or targets executable paths, this may lead to code execution, privilege escalation, data corruption, or denial of service.

Reproduction

Environment

OS: Ubuntu 24.04
Node.js: v24.12.0
compressing: 2.0.0

Construct PoC Archive

The following pseudo-code demonstrates the attack logic:

base_dir = "archive/"
with tarfile.open("./poc_arbitrary_write.tar", mode="w") as tar:
    add_regular_file(tar, base_dir + "baseFile.txt", "base content\n")
    add_symlink(tar, base_dir + "myTmp", "/tmp")
    add_regular_file(tar, base_dir + "myTmp/poc.txt", "Arbitrary File Write\n")

Extract the Archive

const compressing = require('compressing');

function untar(archiveName, destPath) {
  return compressing.tar.uncompress(archiveName, destPath);
}


async function main() {
  const archivePath = process.argv[2];
  const destPath = "./output";

  if (archivePath && archivePath.endsWith(".tar")) {
    await untar(archivePath, destPath);
  }
}

main();

Attack Results

After extraction, the output directory contains a symlink pointing to /tmp. The file poc.txt is then written through the symlink to /tmp/poc.txt, demonstrating an arbitrary file write outside the extraction directory.

Summary

compressing restores symlinks from TAR archives without validating their targets. By combining a malicious symlink with a subsequent file entry, an attacker can redirect extracted files to arbitrary locations on the host.

Severity

8.4 (High)

Mitigation MIT-48.1

Architecture and Design

Strategy: Separation of Privilege

Follow the principle of least privilege when assigning access rights to entities in a software system.
Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.

CAPEC-132: Symlink Attack

An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.

CAPEC-17: Using Malicious Files

An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
