Security audit

ThingsBot

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a straightforward ThingsBoard API helper, but it ships default credentials and documents high-impact operations without enough safeguards.

Review this skill before installing. Use it only against a ThingsBoard server you control, replace the bundled credentials with unique least-privilege credentials, avoid committing credentials.json, use HTTPS for any non-local server, and require explicit confirmation before deleting telemetry or making dashboards public.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill documents a destructive telemetry deletion operation without any warning that the action may be irreversible or data-destructive. In an agent context, this increases the chance of accidental deletion of production telemetry or historical records by users who may treat examples as safe defaults.

No source excerpt is available for this finding.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill describes making dashboards public and retrieving public dashboard info without warning that this may expose sensitive operational, telemetry, or tenant information to unauthenticated users. In an automation setting, users may unknowingly publish internal dashboards and create unintended public access.
