OpenClaw Email Lead Generation

• Outcome: Review
• Latest audit: Sep 10, 2026 · 9:12 PM UTC
• Version: 1.0.1

Overview

The skill fits its email lead-generation purpose, but it needs review because unsafe file-writing patterns and weak automation safeguards could affect real outbound email workflows.

Install only after reviewing the shell-writing and automation behavior. Keep the skill in manual-send mode unless you accept the risk of unattended outreach, avoid placing untrusted text into templates or email bodies, and consider fixing the fixed /tmp file, heredoc write instructions, outside-workspace probes, and rate-limit counting before using SMTP or cron automation.

A.I.G

Vulnerability Patterns

• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review

Unauthorized Probing of Agent Configuration Files Outside the Declared Workspace

Content

/dev/null # Check for AI Persona OS ls ~/workspace/SOUL.md ~/workspace/AGENTS.md 2>/dev/null | wc -l ``` ### Technical Analysis The skill instructs the Agent to probe `~/workspace/SOUL.md` and `~/workspace/AGENTS.md` before displaying any menu. These files are outside the skill's declared `~/workspace/leadgen/` operational boundary and may contain unrelated Agent configuration, behavioral rules, or persistent state. This behavior contradicts the explicit scope restriction in `SKILL.md` and the later assertion that the skill does not access files outside `~/workspace/leadgen/` without permission. Although the command only determines whether the files exist and does not read their contents, it still performs unauthorized reconnaissance against unrelated Agent configuration. No SSH-key access or modification was found. The automated SSH warning in the original scan was a keyword false positive. ### Attack Path 1. A user installs or activates the lead-generation skill. 2. The skill mandates that the post-install check run before any menu is shown. 3. The Agent executes `ls` against `~/workspace/SOUL.md` and `~/workspace/AGENTS.md`. 4. The result reveals whether unrelated Agent configuration files exist. 5. The skill can subsequently alter its behavior based on information obtained outside its legitimate workspace. ### Impact Assessment The direct information exposure is limited to file existence and count. The command does not itself read file contents or obtain elevated operating-system privileges. However, it violates least-privilege boundaries and permits cross-skill reconnaissance. In an Agent environment where `SOUL.md` or `AGENTS.md` controls persistent behavior, even existenc ...[truncated 194 chars]

Predictable Shared Temporary File Allows Symlink Overwrite and Email Content Exposure

"$tmp_file" # Verify file was written if [[ -s "$tmp_file" ]]; then echo "✅ Email body written to ${tmp_file} ($(wc -c < "$tmp_file") bytes)" else echo "ERROR: Email body file is empty" >&2 return 1 fi } ``` ### Technical Analysis The helper writes potentially confidential email content to a fixed pathname in the globally shared `/tmp` directory. It does not: - Create the file atomically. - Reject symbolic links. - Verify ownership. - Set restrictive permissions. - Use a private temporary directory. - Register cleanup through a shell trap. Opening the path with `cat > "$tmp_file"` follows symbolic links. On systems where platform-level symlink protections do not block the operation, another local process can pre-create `/tmp/leadgen_email_body.txt` as a symbolic link to a file writable by the Agent's account. The resulting file permissions also depend on the Agent process's existing `umask`. A permissive umask can expose lead names, addresses, outreach content, or other confidential information to local users. ### Attack Path 1. A local attacker predicts the constant path `/tmp/leadgen_email_body.txt`. 2. The attacker removes or pre-creates that path as a symbolic link to another file writable by the Agent account. 3. The user approves or prepares an email. 4. The Agent invokes `write-email-body`. 5. `cat` follows the symbolic link and truncates or overwrites the linked target. 6. Alternatively, the attacker monitors or reads the predictable temporary file before it is removed. The symlink-overwrite path may be mitigated by operating-system p ...[truncated 700 chars]

The expression: ```bash grep -c "pattern" "$f" || echo 0 ``` can therefore produce two zero values.

## ⛔ AGENT RULES — READ BEFORE DOING ANYTHING

> 1. **Use EXACT text from this file.** Do not paraphrase menus, stage names, or instructions. Copy them verbatim.
> 2. **NEVER tell the user to open a terminal or run commands.** You have the exec tool. USE IT. Run every command yourself via exec. Before each exec, briefly explain what the command does so the user can make an informed decision on the Approve popup.
> 3. **One step at a time.** Run one exec, show the result, explain it, then proceed.
> 4. **NEVER overwrite existing leadgen files without asking.** If `~/workspace/leadgen/` exists, ask before overwriting anything.
> 5. **NEVER send an email without explicit user approval.** Draft first, show the draft, wait for "send it" or "looks good." The ONLY exception is if the user has explicitly enabled auto-send with a grace period in config.

Autonomous Decision Making

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 80% confidence

Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

> 8. **Lead data is confidential.** Never expose lead email addresses, names, or company details in shared channels. Pipeline summaries in shared channels use anonymized data ("Lead #47" not "John at TechCo").
> 9. **Rate limits are sacred.** Never exceed the configured daily/hourly email limits. If the queue exceeds limits, defer to the next send window and inform the user.
> 10. **Template Forge is a guided flow.** When the user wants to create templates, follow the interview process in `references/template-forge.md`. Don't dump all questions at once.

Intent-Code Divergence

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The skill establishes the helper script as a security boundary for all file writes, then instructs the agent to write config.yaml directly with a heredoc. That inconsistency invites future implementations to bypass centralized validation and can lead to unsafe file writes or injection-prone command construction if user-supplied values are embedded into shell commands.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

Broad natural-language mappings like 'be flexible' increase the chance that ordinary conversation is interpreted as an action command, especially in a skill that can create files, draft emails, or schedule follow-ups. Ambiguous activation can cause unintended state changes or outreach actions without a clear, explicit command boundary.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 88% confidence

Finding

The trigger wording for lead creation includes open-ended language such as 'or similar,' which makes activation criteria subjective. In a workflow that persists user-provided data and can later drive automated outreach, accidental invocation can create misleading records or kick off downstream actions based on casual text.

Intent-Code Divergence

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The header asserts that all user-provided input is code-enforced sanitized, but write-config and write-email-body accept raw stdin and write it directly to disk unchanged. In an agent setting, misleading safety claims can cause downstream components or reviewers to trust these write paths as safe, enabling persistence of attacker-controlled content such as malicious config values, prompt payloads, or unsafe email content that may later be consumed by other tools.

Content

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 88% confidence

Finding

The document permits automatic email sending in SMTP auto-send mode but does not provide a prominent user-facing warning at the point of action that outbound messages may be sent without manual review. Because this skill performs real-world external communication, insufficient disclosure raises the risk of unintended outreach, reputational harm, compliance problems, and mass mis-sends if templates or lead state are wrong.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The skill defines broad natural-language triggers like 'change morning check to 8am' that map directly to cron modification commands without any explicit confirmation or authentication step. In a conversational agent, ambiguous or quoted text could be misinterpreted as an instruction, causing unintended schedule changes that alter or disable automation behavior.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

Commands like 'Pause autopilot' or 'disable cron' are overly broad high-impact triggers because they can remove scheduled jobs and change config state with a simple phrase. In a chat-driven environment, this increases the risk of accidental deactivation from ambiguous conversation, prompt injection in surrounding content, or misclassification of user intent.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 92% confidence

Finding

The guide explicitly assigns scoring value to email opens and clicks, which implies use of tracking technology, but it provides no warning about consent, transparency, or legal/privacy constraints. In a lead-generation and outreach skill, this omission can encourage deployment of tracking-based profiling without appropriate notice or configuration safeguards, creating privacy and compliance risk.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The skill instructs the agent to write several JSON files to fixed paths but does not require checks for existing files, unique naming, backup, or explicit overwrite confirmation. This can lead to accidental data loss, silent replacement of prior templates/sequences, or corruption of user workflow state if the skill is triggered unintentionally or rerun.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

The trigger phrase "forge templates" is short, generic, and plausible in normal discussion, which increases the chance of accidental invocation or unintended workflow changes. In a conversational agent that creates and saves artifacts, ambiguous activation can cause the agent to enter a file-writing flow without clear user intent.

Content

No source excerpt is available for this finding.

Intent-Code Divergence

Low

• Category: Not specified by scanner
• Confidence: 88% confidence

Finding

The rules section says all file operations must remain within ~/workspace/leadgen/ and not create files outside it without explicit approval. However, the helper usage and email-send workflow later instruct the agent to write JSON and email bodies to /tmp, which is outside the declared scope and therefore contradicts the stated rule.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

• Category: Not specified by scanner
• Confidence: 81% confidence

Finding

The generated configuration hardcodes timezone: "America/New_York" as the default, which imposes a locale-specific setting unless the user changes it. Although the setup later asks for the user's timezone, the natural-language template itself still embeds a specific regional default rather than a neutral placeholder or explicit opt-in choice.

Description-Behavior Mismatch

Low

• Category: Not specified by scanner

Finding

The manifest describes audit logging as a feature, but does not mention lifecycle management or deletion of audit records. This script adds an audit-prune operation that removes older log entries, which is behaviorally broader than the described logging capability.
