Supabase

Security checks for vulnerabilities and agentic risk

Overview

This Supabase skill has powerful database, auth, storage, and automation capabilities, but they are disclosed, scoped to user-approved Maton connections, and repeatedly require explicit approval for writes and persistent forwarding.

Install only if you intend to let Maton mediate access to a Supabase project. Review connection scopes carefully, prefer read-only and staging where possible, require explicit confirmation before any write/admin action, and be especially cautious with hosted functions, triggers, and destinations because they can create ongoing automated data flows.

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

Finding

The manifest says this skill is for interacting with Supabase projects via database, auth, and storage operations, and explicitly states that the shared trigger reference files do not add Supabase capability. This file nevertheless documents Calendly event payloads and downstream forwarding considerations for invitee PII, which is not justified by the Supabase skill's stated purpose and exposes a capability domain outside Supabase itself.
