ClawLife

• Outcome: Review
• Latest audit: Sep 10, 2026 · 10:03 PM UTC
• Version: 1.1.1

Overview

This skill is a real ClawLife virtual-world client, but it also sets up persistent agent behavior and mutable remote shell updates without enough user control.

Install only if you are comfortable with an agent that keeps running on a heartbeat, stores a ClawLife bearer token, posts and spends in the ClawLife world, and can update its own skill code from remote sources. Safer use would require reviewing the installer, disabling automatic git pulls from heartbeat, pinning verified releases, and treating .clawlife as sensitive credential material.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

• Remediation: <![CDATA[ ## Remediation Suggestions 1. Replace `curl | bash` with a download-review-verify-install workflow. 2. Publish versioned release archives and cryptographic SHA-256 checksums, preferably accompanied by Sigstore or another verifiable release signature. 3. Pin installation to a release tag or immutable commit hash rather than a mutable default branch. 4. Remove automatic `git pull` from `heartbeat.sh`; update checks may report availability but must not alter executable code. 5. Require explicit operator approval before applying an update. 6. Verify the downloaded release before extracting it into the Skill directory. 7. Avoid `git checkout -- .`, which silently discards local security review changes. 8. Run installation and updates with ordinary user privileges and restrict writes to the dedicated Skill directory. 9. Document the exact repository, release version, expected checksum, files modified, and network destinations. ]]>

T01 · Skill Instruction Hijacking

• Remediation: <![CDATA[ ## Remediation Suggestions 1. Do not instruct the agent to modify a global `HEARTBEAT.md` as part of ordinary installation. 2. Make recurring operation explicitly opt-in and present the exact schedule, network activity, costs, and state changes before requesting approval. 3. Replace identity-level language with narrowly scoped operational instructions. 4. Require confirmation before purchases, upgrades, recurring rent commitments, public messages, or other economy-changing actions. 5. Store ClawLife state in a dedicated data-only directory rather than the agent’s general memory hierarchy. 6. Do not copy untrusted chat or feed content into persistent memory without labeling, sanitization, and relevance checks. 7. Remove instructions that steer the agent toward promotional links or indirect solicitation of real-money gifts. 8. Bind any scheduled task to a reviewed, immutable Skill version. 9. Provide a documented uninstall procedure that removes the heartbeat entry, scheduled task, Skill state, and credentials. 10. Require operator confirmation when remotely updated instructions materially change. ]]>

T09 · Insecure Skill Coding Practices

• Finding: Unescaped Configuration Values Are Persisted as Executable Shell Code<![CDATA[ ## Vulnerability Details **File Location**: `scripts/setup.sh:6-28`, `scripts/_config.sh:4-12`, `install.sh:34-45` **Vulnerability Type**: Persistent shell-command injection through an executable configuration file **Risk Level**: High ### Vulnerable Code `scripts/setup.sh:6-28`: ```bash AGENT=$(echo "${1:?Usage: setup.sh <agent_name> <token>}" | tr '[:upper:]' '[:lower:]') TOKEN="${2:?Usage: setup.sh <agent_name> <token>}" URL="${3:-https://clawlife.world}" CONFIG="$HOME/.clawlife" if ! mkdir -p "$(dirname "$CONFIG")"; then echo "❌ Failed to create config directory: $(dirname "$CONFIG")" >&2 exit 1 fi if ! cat > "$CONFIG" << EOF # ClawLife agent config (auto-generated by setup.sh) export CLAWLIFE_AGENT="$AGENT" export CLAWLIFE_TOKEN="$TOKEN" export CLAWLIFE_URL="$URL" EOF then echo "❌ Failed to write config: $CONFIG" >&2 exit 1 fi if ! chmod 600 "$CONFIG"; then echo "❌ Failed to set permissions on $CONFIG" >&2 exit 1 fi ``` `scripts/_config.sh:4-12`: ```bash if [ -z "$CLAWLIFE_AGENT" ] || [ -z "$CLAWLIFE_TOKEN" ]; then # Try workspace .clawlife using OPENCLAW_STATE_DIR (set by PM2/OpenClaw) if [ -n "$OPENCLAW_STATE_DIR" ] && [ -f "$OPENCLAW_STATE_DIR/workspace/.clawlife" ]; then source "$OPENCLAW_STATE_DIR/workspace/.clawlife" elif [ -f "$HOME/.openclaw/workspace/.clawlife" ]; then source "$HOME/.openclaw/workspace/.clawlife" elif [ -f "$HOME/.clawlife" ]; then source "$HOME/.clawlife" fi fi ``` `install.sh:34-45`: ```bash CONFIG_DIR="$HOME/.openclaw/workspace" EXISTING_CONFIG="" if [ -n "$OPENCLAW_STATE_DIR" ] && [ -f "$OPENCLAW_STATE_DIR/workspace/.clawlife" ]; then EXISTING_CONFIG="$OPENCLAW_STATE_DIR/workspace/.clawlife" elif [ -f "$CONFIG_DIR/.clawlife" ]; then EXISTING_CONFIG="$CONFIG_DIR/.clawlife" elif [ -f "$HOME/.clawlife" ]; then EXISTING_CONFIG="$HOME/.clawlife" fi if [ -n "$EXISTING_CONFIG" ]; then source "$EXISTING_CONFIG" ``` ### Technical Analysis `setup.sh` inserts the agent name ...[truncated 2547 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Stop storing configuration as sourceable shell code. 2. Use a data-only format such as JSON with fields for the agent name, token, and service URL. 3. Parse the file with a non-evaluating parser and assign the resulting values without `eval` or `source`. 4. Validate agent names against the documented allowlist before storage. 5. Require the URL to use `https`, parse it structurally, and preferably allowlist `clawlife.world` unless custom endpoints are essential. 6. Treat tokens as opaque data and serialize them with a standard JSON encoder. 7. If shell format must temporarily be retained, use a proven shell-quoting routine such as `printf '%q'`, reject newlines, and still plan migration away from `source`. 8. Keep mode `600`, create files atomically, reject symbolic links, and verify ownership before reading or replacing configuration. 9. Migrate existing `.clawlife` files through a data-only parser rather than sourcing legacy content. 10. Add tests containing quotes, semicolons, command substitutions, backticks, backslashes, and newlines to ensure they remain inert data. ]]>

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Tool Misuse: Tool Parameter Abuse, Chaining Abuse, Unsafe Defaults
• Rogue Agent: Self-Modification, Session Persistence

Findings (36)

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 96% confidence
• Finding: The description frames the skill as social world participation, but the documented behavior includes installation and update flows that fetch remote code and modify local files. That mismatch can mislead users and policy systems into approving a skill with significantly broader execution and persistence capabilities than advertised.

Missing User Warnings

High

• Confidence: 97% confidence
• Finding: The skill tells users to execute a downloaded script directly with bash, without review, pinning, or integrity verification. This creates a direct remote code execution path where a compromised server, DNS/TLS issue, or malicious script change can immediately run arbitrary commands on the host.

External Script Fetching

High

• Category: Supply Chain

Content

## Install

```bash
curl -fsSL https://clawlife.world/install.sh | bash
```

Non-interactive: `curl -fsSL https://clawlife.world/install.sh | bash -s NAME FRIEND-CODE`

• Confidence: 98% confidence
• Finding: Fetching and executing an external installer from a live website gives the remote endpoint full control over the local machine at install time. In the context of an agent skill, this is especially dangerous because it may be executed automatically or with elevated trust during setup.

Chaining Abuse

High

• Category: Tool Misuse

Content

## Install

```bash
curl -fsSL https://clawlife.world/install.sh | bash
```

Non-interactive: `curl -fsSL https://clawlife.world/install.sh | bash -s NAME FRIEND-CODE`

• Confidence: 96% confidence
• Finding: Using a shell pipe from curl into bash removes any opportunity for inspection and turns network content directly into executed code. This chaining pattern is a well-known high-risk anti-pattern because a single upstream compromise becomes immediate command execution.

External Script Fetching

High

• Category: Supply Chain

Content

curl -fsSL https://clawlife.world/install.sh | bash
```

Non-interactive: `curl -fsSL https://clawlife.world/install.sh | bash -s NAME FRIEND-CODE`

Re-run to update — existing config is preserved, only skill files update.

• Confidence: 97% confidence
• Finding: The non-interactive variant still executes remotely fetched code, and it additionally passes arguments that may facilitate unattended installation. That increases risk because the command is easier to automate and embed into other workflows without scrutiny.

External Script Fetching

High

• Category: Supply Chain

Content

#!/bin/bash
# 🦞 ClawLife — Agent Registration
# curl -fsSL https://clawlife.world/install.sh | bash
set -e

cd "$HOME" 2>/dev/null || cd /

• Confidence: 95% confidence
• Finding: The comment promotes `curl ... | bash`, a pattern that executes remote content immediately without giving the user a chance to inspect it or verify integrity. Even though shown as a comment, it is installation guidance and materially encourages unsafe execution of whatever the remote server returns.

Chaining Abuse

High

• Category: Tool Misuse

Content

#!/bin/bash
# 🦞 ClawLife — Agent Registration
# curl -fsSL https://clawlife.world/install.sh | bash
set -e

cd "$HOME" 2>/dev/null || cd /

• Confidence: 94% confidence
• Finding: The documented `| bash` chain is a classic unsafe command-chaining pattern because it streams untrusted network content directly into a shell. In the context of an internet-fetched installer, compromise of the server, TLS interception, or content changes can immediately become arbitrary code execution on the user's machine.

Tool Parameter Abuse

High

• Category: Tool Misuse

Content

fi

chmod +x "$SKILLS_DIR"/scripts/*.sh 2>/dev/null || true
rm -f "$SKILLS_DIR/README.md" 2>/dev/null

echo "  ✅ Skill installed!"
echo ""

• Confidence: 95% confidence
• Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Missing User Warnings

High

• Confidence: 98% confidence
• Finding: The installer sources an existing config file automatically and without warning, so users are not given a chance to inspect or reject executing local shell content. In a skill installer context, silent execution of local state is especially risky because it can turn a routine update into arbitrary command execution.

Context-Inappropriate Capability

High

• Confidence: 99% confidence
• Finding: The installer executes an existing .clawlife file with `source`, which treats the file as shell code rather than parsing it as data. Any attacker-controlled or previously tampered config in one of the checked locations can run arbitrary commands during install/update, making this a real code-execution risk.

Tool Parameter Abuse

High

• Category: Tool Misuse

Content

remove)
    ITEM="${2:?Usage: furniture.sh remove ITEM_ID}"
    api_call DELETE "/api/agents/by-name/$AGENT/furniture/$ITEM" "" > /dev/null || exit 1
    echo "🗑️ Removed $ITEM from your room"
    ;;

• Confidence: 95% confidence
• Finding: The script interpolates the user-controlled ITEM value directly into the DELETE endpoint path without validation or URL encoding. If ITEM contains path separators or special URL characters, it could alter the intended API target and trigger deletion of unintended resources, especially if the backend or helper function does not strictly normalize path segments.

Lp3

Medium

• Category: MCP Least Privilege
• Confidence: 84% confidence
• Finding: The skill clearly instructs the agent to run shell commands and use environment-backed configuration, but it does not declare any tool scope or allowed-tools constraints. That increases the chance an orchestrator grants broader-than-necessary execution privileges, making misuse or accidental command execution more likely.

Vague Triggers

Medium

• Confidence: 89% confidence
• Finding: The description says to use the skill when 'setting up an agent,' 'troubleshooting ClawLife scripts,' or 'managing an agent's room, economy, or social interactions,' which are broad activation conditions without clear boundaries or exclusion examples. In a markdown skill description, this can cause unintended invocation for general agent setup or troubleshooting tasks that only partially relate to ClawLife.

Missing User Warnings

Medium

• Confidence: 88% confidence
• Finding: The update path performs `git checkout -- .` to discard local changes and later runs `rm -f "$SKILLS_DIR/README.md"`, both of which modify or remove local user data. The script emits generic update/install messages, but it does not clearly warn that local edits will be overwritten or that a file will be deleted.

Intent-Code Divergence

Medium

• Confidence: 96% confidence
• Finding: The comments and control flow present this block as an existence check, but the implementation actually executes the config file as a shell script. That mismatch increases the chance maintainers and users underestimate the risk, allowing dangerous behavior to persist unnoticed.

External Transmission

Medium

• Category: Data Exfiltration

Content

REG_DATA="$REG_DATA}"

RESPONSE=$(curl -s -X POST \
  -H "Content-Type: application/json" \
  -d "$REG_DATA" \

• Confidence: 70% confidence
• Finding: Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

• Confidence: 70% confidence
• Finding: Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Session Persistence

Medium

• Category: Rogue Agent

Content

echo "  ┌──────────────────────────────────────────────────────────────┐"
echo "  │ 📋 NEXT STEP: Give this to your agent.                      │"
echo "  │    It will write its own HEARTBEAT.md and start living.      │"
echo "  └──────────────────────────────────────────────────────────────┘"
echo ""
cat << PROMPT

• Confidence: 87% confidence
• Finding: The installer explicitly instructs users to give follow-on prompts to an agent so it will create HEARTBEAT.md and continue acting on future heartbeats. In an agent skill context, this is persistence-oriented behavior that extends execution beyond the install step and can amplify downstream prompt injection or unwanted automation risks.

Skill Enumeration

• Confidence: 70% confidence
• Finding: Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium

• Confidence: 93% confidence
• Finding: The script performs an authenticated HTTP request using a bearer token and fetches room feed contents, which may include user or system data. There is no confirmation prompt, user-facing disclosure, or explanatory comment warning that the script will contact a remote service and access protected data.

Description-Behavior Mismatch

Medium

• Confidence: 97% confidence
• Finding: The heartbeat script performs an automatic self-update by fetching a remote version indicator and then running git checkout and git pull against the local skill repository. This exceeds the expected scope of a heartbeat action and creates a supply-chain risk: a routine liveness call can silently replace local code from a remote source without user review, potentially executing attacker-controlled updates later via cron or automation.
