OpenTable

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent advisory OpenTable operations skill that stores limited local notes and does not automate account access or hidden data collection.

Install only if you want Codex to keep local OpenTable operations notes. Do not put credentials, tokens, payment data, or detailed guest personal information into the markdown files; use the skill as an advisory playbook unless you separately configure trusted OpenTable integrations.

A.I.G

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

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.

- avoid storing sensitive guest details in long-lived notes
- document only what is required for operational decisions

Never ask users to paste credentials or private account tokens into chat.

md
| Class | Typical Symptom | Immediate Priority |
|------|------------------|--------------------|
| Overbooking | More covers than seatable capacity | Protect in-house service and communicate options |
| Confirmation failure | Guests claim no confirmation or wrong time | Reconcile reservation state and reduce arrival friction |
| Availability mismatch | Slots shown despite operational block | Stop new exposure and correct inventory quickly |
| Outage or degraded platform | Booking flow unavailable or unstable | Activate fallback intake and preserve guest trust |

Sudo/Root Execution

Finding

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