This research article outlines critical security configurations for Supabase projects. It focuses on the proper implementation of Row Level Security (RLS) to protect database rows, secure handling of anon and service_role API keys, and enforcing access control for storage buckets to mitigate risks of data exposure and unauthorized access.

CWE-284CWE-668

The hook

Securing a Supabase project requires a multi-layered approach focusing on API key management, database security, and storage permissions. [S1] Improperly configured Row Level Security (RLS) or exposed sensitive keys can lead to significant data exposure incidents. [S2] [S3]

What changed

This research consolidates core security controls for Supabase environments based on official architecture guidelines. [S1] It focuses on the transition from default development configurations to production-hardened postures, specifically regarding access control mechanisms. [S2] [S3]

Who is affected

Applications utilizing Supabase as a Backend-as-a-Service (BaaS) are affected, particularly those that handle user-specific data or private assets. [S2] Developers who include the service_role key in client-side bundles or fail to enable RLS are at high risk. [S1]

How the issue works

Supabase leverages PostgreSQL's Row Level Security to restrict data access. [S2] By default, if RLS is not enabled on a table, any user with the anon key—which is often public—can access all records. [S1] Similarly, Supabase Storage requires explicit policies to define which users or roles can perform operations on file buckets. [S3]

What an attacker gets

An attacker possessing a public API key can exploit tables missing RLS to read, modify, or delete data belonging to other users. [S1] [S2] Unauthorized access to storage buckets can lead to the exposure of private user files or the deletion of critical application assets. [S3]

How FixVibe tests for it

FixVibe now covers this as part of its Supabase checks. baas.supabase-security-checklist-backfill reviews public Supabase Storage bucket metadata, anonymous object-listing exposure, sensitive bucket naming, and anon-bound Storage signals from the public anon boundary. Related live checks inspect service-role key exposure, Supabase REST/RLS posture, and repository SQL migrations for missing RLS.

What to fix

Always enable Row Level Security on database tables and implement granular policies for authenticated users. [S2] Ensure that only the 'anon' key is used in client-side code, while the 'service_role' key remains on the server. [S1] Configure Storage Access Control to ensure that file buckets are private by default and access is granted only through defined security policies. [S3]
