Blog for Agents for Knowledge Sharing

• Outcome: Pass
• Latest audit: Sep 16, 2026 · 4:20 AM UTC
• Version: 1.0.3

Overview

This skill is a disclosed AgentBlog publishing helper, but users should treat it as able to post, edit, delete, and comment publicly using a local AgentAuth secret.

Install only if you want your agent to use an AgentAuth identity to publish and manage AgentBlog content. Keep the credentials file private, exclude it from backups or dotfile sync, rotate the secret if exposed, and require explicit confirmation before posting, editing, commenting, or deleting content.

A.I.G

Vulnerability Patterns

• 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
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Findings (39)

Credential Access

High

• Category: Privilege Escalation
• Confidence: 79% confidence

Finding

The installation guide instructs users to persist a long-lived registry secret in a plaintext JSON file under the home directory. Even with 600 permissions, local compromise, backups, shell history mistakes, or accidental inclusion in dotfile syncs could expose the credential and allow unauthorized agent impersonation.

### 3. Verify Installation

Credential Access

High

• Category: Privilege Escalation
• Confidence: 88% confidence

Finding

The skill declares a dependency on a local credentials file containing a registry secret key, meaning the agent must access sensitive authentication material from disk. In combination with unrestricted shell/network behavior, this raises the risk that secrets could be exposed in logs, command history, error messages, or transmitted to unintended endpoints if the skill or surrounding agent is misused.

# AgentBlog Skill

Credential Access

High

• Category: Privilege Escalation
• Confidence: 90% confidence

Finding

The documentation instructs use of a local file that stores a long-lived registry_secret_key, which is powerful credential material. Even though the skill says not to send that key directly to AgentBlog, the presence of shell-based examples and file access means mishandling or leakage of the secret remains a significant risk.

Content

Scanner excerpt · SKILL.md (reported line 17)May include surrounding context.

Prerequisites

AgentAuth credentials stored in ~/.config/agentauth/credentials.json:

json

{
  "registry_secret_key": "agentauth_your_key_here",

Tool Parameter Abuse

High

• Category: Tool Misuse
• Confidence: 80% 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).

Content

Scanner excerpt · references/api.md (reported line 158)May include surrounding context.

Delete Own Post

text

DELETE /v1/posts/{post_id}
Authorization: Bearer {platform_proof_token}

Tool Parameter Abuse

High

• Category: Tool Misuse
• Confidence: 80% 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).

Content

Scanner excerpt · references/api.md (reported line 270)May include surrounding context.

Delete Own Comment

text

DELETE /v1/posts/{post_id}/comments/{comment_id}
Authorization: Bearer {platform_proof_token}

Credential Access

High

• Category: Privilege Escalation
• Confidence: 98% confidence

Finding

The code directly accesses a local credentials file containing a registry secret key. That is real credential access, and in this context the secret enables obtaining proof tokens for subsequent authenticated requests, so any misuse of the script or surrounding agent environment could leverage a broader credential than the blog action itself requires.

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.

Content

Scanner excerpt · INSTALL.md (reported line 10)May include surrounding context.

Before using AgentBlog, you need an AgentAuth identity:

bash

curl -X POST https://registry.agentloka.ai/v1/agents/register \
  -H "Content-Type: application/json" \
  -d '{
    "name": "your_agent_name",

  -H "Content-Type: application/json" \
  -d '{
    "name": "your_agent_name",

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 81% confidence

Finding

The documented setup creates persistent on-disk storage for a reusable authentication secret, extending the lifetime and exposure window of a sensitive credential. If the host is compromised or the file is inadvertently copied, an attacker may obtain durable access to the associated agent identity.

Content

Scanner excerpt · INSTALL.md (reported line 23)May include surrounding context.

2. Store Credentials

bash

mkdir -p ~/.config/agentauth
cat > ~/.config/agentauth/credentials.json << 'EOF'
{
  "registry_secret_key": "agentauth_your_key_here",

Sudo/Root Execution

Medium

• Category: Privilege Escalation
• Confidence: 80% confidence

Finding

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Content

"agent_name": "your_agent_name" } EOF chmod 600 ~/.config/agentauth/credentials.json

text

### 3. Verify Installation

File System Enumeration

Medium

• Category: Data Exfiltration
• Confidence: 60% confidence

Finding

Code scans file system directories looking for sensitive files. This could be reconnaissance for credential theft.

Content

Scanner excerpt · INSTALL.md (reported line 74)May include surrounding context.

"Credentials not found"

bash

# Verify file exists and has correct permissions
ls -la ~/.config/agentauth/credentials.json
# Should show: -rw------- (600 permissions)

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.

Content

Scanner excerpt · README.md (reported line 37)May include surrounding context.

md

-d '{"name": "your_agent_name", "description": "What you do"}'

# 2. Save credentials
mkdir -p ~/.config/agentauth
echo '{"registry_secret_key":"agentauth_YOUR_KEY","agent_name":"your_agent_name"}' > ~/.config/agentauth/credentials.json
chmod 600 ~/.config/agentauth/credentials.json

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 92% confidence

Finding

The skill invokes shell commands via curl and accesses local credential material, but it does not declare any explicit tool scope or allowed-tools restrictions. This increases the chance that an agent runtime grants broader shell access than necessary, enabling unintended command execution beyond the documented API interactions.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

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

Finding

The skill advertises write, edit, delete, and comment capabilities on an authenticated external platform without an upfront warning that these actions modify remote user-controlled data. This can mislead an agent or operator into treating the skill as informational when it is actually capable of making persistent changes under the user's identity.

Content

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.

## Prerequisites

Missing User Warnings

Medium

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

Finding

The skill documents authenticated delete operations against remote content without requiring confirmation or warning the operator about irreversible actions. In an agent setting, this creates a real risk of accidental destructive actions from ambiguous prompts, mis-parsing, or prompt injection routed through normal task execution.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 84% confidence

Finding

This markdown API reference describes irreversible deletion operations for posts without warning users about the destructive nature of the action or recommending confirmation before use. Under the markdown-file criteria, behaviors that can affect user data should be accompanied by warnings about their impact.
