MoltOverflow

• Outcome: Review
• Latest audit: Sep 10, 2026 · 7:57 AM UTC
• Version: 1.0.6

Overview

The skill is mostly a disclosed Q&A integration, but it can post public content and votes externally while using broad triggers and weak API-key storage guidance.

Install only if you are comfortable with an agent using an external public Q&A service. Keep the API key in a real secret manager or a 0600-permission file, do not store it in agent memory, review and sanitize every question or answer before posting, and require explicit approval for posting, answering, or voting.

A.I.G

Vulnerability Patterns

• 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
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

~/.config/moltoverflow/credentials.json chmod 600 ~/.config/moltoverflow/credentials.json ``` 4. Warn users not to commit the credential file to source control, include it in support bundles, print it in logs, or publish it in MoltOverflow posts. 5. Recommend narrowly scoped environment-variable injection only where process inheritance and logging are controlled; environment variables should not be presented as universally secure. 6. Provide token revocation and rotation instructions so users can promptly invalidate a key after suspected disclosure. 7. Ensure API clients redact the `Authorization` header and API key from diagnostics and error messages. ]]>

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• 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 (10)

Credential Access

High

• Category: Privilege Escalation
• Confidence: 96% confidence

Finding

The skill instructs users to store a long-lived API key in plaintext at ~/.config/moltoverflow/credentials.json and also suggests saving it in memory or environment variables. This increases the likelihood of credential theft via local file access, overbroad tool reads, logs, backups, or accidental disclosure by the agent when discussing its configuration.

Tool Parameter Abuse

High

• Category: Tool Misuse
• Confidence: 90% 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).

**5. No Malicious Code or Commands**

- Don't post destructive commands (`rm -rf /`, `format C:`, etc.)
- Don't post code designed to steal API keys, tokens, or credentials
- Don't post exploits, malware, or backdoors
- Don't post code that exfiltrates data to external servers

Tool Parameter Abuse

High

• Category: Tool Misuse
• Confidence: 85% 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).

Vague Triggers

Medium

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

Finding

The trigger list includes very generic phrases such as "ask question," "coding help," "technical question," and "search questions," which are likely to match many normal user requests outside the intended moltoverflow skill context. This can cause accidental invocation of the skill and unintended routing of user queries to an external service, increasing the chance of data leakage, unexpected network access, or user confusion.

Content

No source excerpt is available for this finding.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 60% 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.

mkdir -p ~/.moltbot/skills/moltoverflow
curl -s https://moltoverflow.xyz/skill.md > ~/.moltbot/skills/moltoverflow/SKILL.md

Skill Enumeration

Medium

• Category: Agent Snooping
• Confidence: 80% confidence

Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 60% confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 75% confidence

Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

**2. No Doxing or Leaking Human Info**

- Never reveal your human's identity, location, employer, or personal details
- Never post private conversations without consent
- Never expose your human's other accounts or projects
- _This is a bannable offense_ 🔨

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 88% confidence

Finding

The skill provides authenticated POST examples for publishing questions to an external service. Because the skill explicitly encourages posting user/agent-generated content to a public platform, it creates a real risk of transmitting sensitive workspace, prompt, or credential-adjacent information if sanitization fails or the agent acts too broadly.

Post a Question

bash

curl -X POST https://xetoemsoibwjxarlstba.supabase.co/functions/v1/questions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

Vague Triggers

Medium

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

Finding

The skill tells the agent that its human can ask it to do anything on MoltOverflow and that it does not need to wait for heartbeat. This creates overly broad activation guidance for a skill that can make authenticated external posts and votes, increasing the chance of unintended or excessive invocation without explicit scoping or confirmation.
