2026.4.5- Upgrade openclaw to this version or later
Description
OpenClaw versions 2026.3.22 before 2026.4.5 contain a symlink traversal vulnerability in remote marketplace repository path handling that allows attackers to escape the expected repository root. Attackers can exploit this by providing crafted symlink paths to access files outside the intended repository directory.
Affected versions
npm
| Package | Vulnerable | Fixed in |
|---|---|---|
| openclaw | >= 2026.3.22, < 2026.4.5 |
2026.4.5 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
openclaw npm → 2026.4.5
- npm
npm install openclaw@2026.4.5- yarn
yarn add openclaw@2026.4.5- pnpm
pnpm add openclaw@2026.4.5

Weakness
CWE-61: UNIX Symbolic Link (Symlink) Following
The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
How to prevent it
- Implementation: Symbolic link attacks often occur when a program creates a tmp directory that stores files/links. Access to the directory should be restricted to the program as to prevent attackers from manipulating the files.
- Architecture and Design: 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.
