Summary
OpenClaw: Unsanitized CWD path injection into LLM prompts
Details

Overview

OpenClaw embedded the current working directory (workspace path) into the agent system prompt without sanitization. If an attacker can cause OpenClaw to run inside a directory whose name contains control/format characters (for example newlines or Unicode bidi/zero-width markers), those characters could break the prompt structure and inject attacker-controlled instructions.

Impact

Prompt injection may alter agent behavior and could lead to unintended tool use or disclosure of sensitive information.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Vulnerable versions: < 2026.2.15 (latest published vulnerable version as of 2026-02-16: 2026.2.14)
  • Patched versions: >= 2026.2.15

Fix

The workspace path is now sanitized before it is embedded into any LLM prompt output, stripping Unicode control/format characters and explicit line/paragraph separators. Workspace path resolution also applies the same sanitization as defense-in-depth.
