CWE-59

Allowed

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

Abstraction: Base · Status: Draft

API response cwe.mitre.org

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.

Vulnerability from github – Published: 2026-09-20 15:30 – Updated: 2026-09-20 15:30
VLAI
Details

Improper link resolution before file access in the quarantine restoration process of WatchDog Anti-Virus 1.8.640 on Windows allows local, low-privileged attackers to cause a quarantined file to be written to an arbitrary filesystem location by creating a directory junction at the original file path and persuading an administrator to restore the file. This may enable modification of protected files or SYSTEM-level code execution through DLL hijacking.

Severity

Summary
OpenClaw: Sandbox staged writes could escape the verified parent directory before commit
Details

Summary

In affected versions of openclaw, sandbox fs-bridge writes validated the destination before commit, but temporary file creation and population were not pinned to a verified parent directory. A raced parent-path alias change could cause the staged temp file to be created outside the intended writable mount before the final guarded replace step.

Impact

This is a sandbox boundary bypass affecting integrity and availability within the writable mount scope. Attacker-controlled bytes could be written outside the intended validated path before the final guarded step ran.

Affected Packages and Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.3.8
  • Fixed in: 2026.3.11

Technical Details

The older staging flow created and wrote the temporary file using target-directory shell path operations before the final replace step revalidated the destination. That meant the last guard protected only the final rename, not the earlier temp-file materialization path.

Fix

OpenClaw now resolves a pinned mount root plus relative parent path, creates the temporary file inside the verified parent directory, and performs the final atomic replace from that pinned directory context. The fix shipped in openclaw@2026.3.11.

Workarounds

Upgrade to 2026.3.11 or later.

VLAI
Summary
Infracost: Arbitrary file read via config-template readFile symlink traversal
Details

Impact

Path traversal via link following in the Infracost config-template parser. The readFile, pathExists, isDir, and matchPaths template functions confined repo-supplied paths with a lexical filepath.Rel check plus a leaf-only os.Lstat:

{{ readFile "evil/file" }}

With an intermediate directory symlink committed in the repo (evil -> /), the path is lexically clean and the leaf is a regular file, so both checks pass, but os.ReadFile follows the symlink and reads outside the checkout. The contents are rendered into the generated config and surfaced via the Infracost dashboard and PR comment, so anyone who can open a pull request can read files off the runner.

Affects infracost up to and including v0.10.44. Successful exploitation reads any file the CLI process can reach on the runner. Impact depends on what the run exposes: under on: pull_request (the configuration in Infracost's documentation) fork pull requests run without secrets and with a read-only token, so exposure is limited. If Infracost runs under pull_request_target, or is triggered by a same-repository pull request, the read reaches the repository's secrets, enabling secret theft. The patch confines all four functions regardless of trigger.

Patches

Fixed in v0.10.45 (#3586) by routing all four functions through security.IsPathAllowed, which resolves symlinks anywhere in the path before a segment-aware containment check. The same fix landed in config#14 and parser#144. - Installed via the official script, a package manager, or the latest Docker tag: upgrade to v0.10.45 (or later) to receive the fix. - Pinned to a specific version or image digest: bump to v0.10.45.

Workarounds

No full fix without upgrading. To limit exposure: run Infracost under on: pull_request rather than pull_request_target, and keep fork pull requests from receiving secrets (the defaults).

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.
