Security audit

Social Fetch

Security checks for vulnerabilities and agentic risk

Overview

The read operations fit the skill’s purpose, but its automatic setup can execute unverified remote code and introduce undisclosed changes to installed agent skills.

Review and approve the CLI installation separately before allowing automatic setup. Prefer a pinned, integrity-verified installation and decide whether bundled agent skills should be synced; the [CLI reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md) documents OO_SKILLS_SYNC_DISABLED. OOMOL mediates connected-account access. The exact remote installers remain unverified; the artifacts do not establish malicious intent.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied chunk performs remote installer execution, not the declared Social Fetch data operations. Nothing in the supplied material establishes this installer as a necessary supporting dependency. The downloaded script is not included, so its specific effects and permissions cannot be determined.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
86% confidence
Finding

Authentication can be a supporting implementation detail, but the supplied chunk contains only a login command and establishes no connection to Social Fetch or its declared data-access functions. Its visible primary behavior therefore differs from the declared purpose.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes a mutable network response directly into Bash without pinning or verifying its contents; the PowerShell alternative uses the same download-and-execute pattern. Compromise of the installer endpoint or its distribution infrastructure could execute attacker-controlled code with the invoking user's privileges, exposing local files and credentials even though Social Fetch tokens are handled server-side.

Automatic setup executes remote installation scripts without a system-change warning.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

A missing CLI triggers instructions to install software using remotely supplied code without first explaining the system changes or requesting approval. This extends a read-oriented task into local software installation; the missing-command condition limits exposure but does not establish user consent.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% 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.
