Security audit

tripadvisor-api

Security checks for vulnerabilities and agentic risk

Overview

The skill provides read-only TripAdvisor lookups with disclosed API-key use and an optional browser connection that requires user approval.

Supply your TripAdvisor key through the environment without printing it, and consider API usage charges. If using the optional browser fallback, approve only tripadvisor.com with fetch capability and revoke pairing when finished. The CLI and extension are separate dependencies; their documentation was checked, but their exact release binaries are outside this artifact review.

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

Credential Access

High
Category
Privilege Escalation
Confidence
60% confidence
Finding

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

One-time setup: get a Terra key

sh
# Prefer the env var tripadvisor-mcp itself reads (check its .env first):
grep -h TRIPADVISOR_API_KEY ~/git/tripadvisor-mcp/.env 2>/dev/null
export TRIPADVISOR_API_KEY='...'
