neon-object-storage

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Neon Object Storage documentation skill; it uses expected Neon and S3 credentials but does not show hidden, deceptive, or unrelated behavior.

Before installing, understand that this skill may guide your agent to create or modify Neon buckets, install SDK dependencies, and place branch-scoped S3 credentials in local environment files. Use preview branches for testing, keep .env files out of source control, and review bucket/object delete commands before running them.

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

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.

When buckets is declared, Neon injects AWS-standard S3 env vars so the AWS SDKs work from the environment with zero extra config. Inside a deployed Neon Function these are injected automatically; locally, pull them onto disk (or inject them at runtime) via the CLI:

bash
neon env pull            # writes the branch's vars into .env (or .env.local)
# or, without writing a file, inject at runtime:
neon-env run -- <your dev command>

Skill Enumeration

Confidence
80% confidence
Finding

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

FIRST: Use the parent neon skill for a Neon overview, getting started with Neon, Neon development best practices, and more.

If the neon skill is not installed, fetch it from https://neon.com/docs/ai/skills/neon/SKILL.md or install it with:

bash
