Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: abc123def.supabase.co.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    Hosts contacted

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned yoanbernabeu/supabase-pentest-skills at 0f9612276b.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

The supabase-audit-buckets-public skill enables AI agents to systematically scan Supabase storage buckets for publicly accessible resources. It identifies potential security vulnerabilities where sensitive data might be exposed without authentication, ensuring compliance with privacy standards.

When to use it

  • Pre-deployment security checks: Run this audit before launching a new application to ensure no user-uploaded files are accidentally made public.
  • Post-incident investigation: Quickly locate and secure any buckets that were mistakenly configured as public after a data breach or configuration error.
  • Compliance verification: Validate that storage configurations adhere to GDPR, HIPAA, or other regulations requiring strict access controls on sensitive data.
  • Routine maintenance: Integrate into CI/CD pipelines to automatically flag public bucket changes during the build process.

Key capabilities

  • Scans all Supabase storage buckets for public read/write permissions.
  • Identifies specific files or directories exposed without authentication.
  • Provides a clear report of vulnerable resources requiring immediate remediation.

Example prompts

  • "Audit my Supabase project and list any storage buckets currently set to public access."
  • "Check if the 'user-uploads' bucket in my Supabase instance allows unauthenticated reads or writes."
  • "Scan all tables and buckets for misconfigurations that expose sensitive data publicly."

Tips & gotchas

Ensure your AI agent has read-only access to the Supabase project configuration; attempting to modify buckets directly during an audit could cause unintended side effects. This skill focuses on permission levels, so it may not detect logical vulnerabilities like missing encryption at rest.
