Path Traversal in ZeroClaw Plugin Installation

Publication date: 2026-09-30

Last updated on: 2026-09-30

Assigner: VulnCheck

Description
ZeroClaw versions before 0.8.5 built with plugins-wasm feature contain a path traversal vulnerability in plugin installation that fails to validate the wasm_path manifest field. Attackers can convince users to install crafted plugins that write arbitrary files to paths outside the plugins directory, such as shell startup files, enabling code execution.

Executive Summary

CVE-2026-101885 is a path traversal vulnerability in ZeroClaw versions before 0.8.5 when built with the plugins-wasm feature. It occurs during plugin installation due to improper validation of the wasm_path manifest field. Attackers can craft malicious plugins that write arbitrary files outside the plugins directory, such as shell startup files, enabling code execution.

Detection Guidance

Check for ZeroClaw versions before 0.8.5 by running: zeroclaw --version. Inspect plugin manifests for malicious wasm_path entries containing ../ or absolute paths. Review files in shell startup directories (e.g., ~/.bashrc, ~/.zshrc) for unexpected modifications.

Impact Analysis

This vulnerability allows attackers to write arbitrary files to sensitive locations on your system, such as shell startup files. This could lead to code execution in the context of the installing user, potentially compromising your system or data. The attack requires user interaction to install a crafted plugin.

Mitigation Strategies

Upgrade ZeroClaw to version 0.8.5 or later immediately. Disable the plugins-wasm feature if not required. Avoid installing plugins from untrusted sources. Enable strict plugin signature verification if available.
