GHSA-2qj5-gwg2-xwc4

## 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.

## Fix Commit(s) - `6254e96acf16e70ceccc8f9b2abecee44d606f79`
