Plausible Analytics

Security checks for vulnerabilities and agentic risk

Overview

The analytics workflow has sensible safeguards, but automatic setup runs unpinned downloaded code without requiring your approval.

Approve CLI installation separately and use a reviewed, fixed release. Disable automatic skill synchronization if you only want this analytics integration. OOMOL mediates requests and manages the connected Plausible credentials. The live installers and hosted connector implementation remain unverified; no malicious behavior was established.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied chunk performs remote installer execution rather than Plausible Analytics operations. Nothing shown establishes that this installer is a supporting dependency for the declared functionality. The downloaded script's contents are not supplied, so its further actions cannot be determined.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes a mutable remote script directly into Bash without a pinned version or independent integrity verification. Compromise of the installer hosting or distribution pipeline could execute arbitrary code with the agent's permissions; HTTPS and the legitimate connector setup purpose do not eliminate this supply-chain risk.

Fallback setup executes downloaded installation scripts without warning about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

When the CLI is missing, the skill directs the agent to execute a downloaded installer without explicit user approval or disclosure of local system changes. The fallback condition limits exposure, but an analytics request alone should not authorize arbitrary installation code running with the agent's local permissions.

No source excerpt is available for this finding.

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.
