Attacker Impact
An attacker can gain unauthorized access to sensitive user data, modify database records, or hijack infrastructure by exploiting common oversights in MVP deployments. This includes accessing cross-tenant data due to missing access controls [S4] or using leaked API keys to incur costs and exfiltrate data from integrated services [S2].
Root Cause
In the rush to launch an MVP, developers—especially those using AI-assisted "vibe coding"—frequently overlook foundational security configurations. The primary drivers of these vulnerabilities are:
- Secret Leakage: Credentials, such as database strings or AI provider keys, are accidentally committed to version control [S2].
- Broken Access Control: Applications fail to enforce strict authorization boundaries, allowing users to access resources belonging to others [S4].
- Permissive Database Policies: In modern BaaS (Backend-as-a-Service) setups like Supabase, failing to enable and correctly configure Row Level Security (RLS) leaves the database open to direct exploitation via client-side libraries [S5].
- Weak Token Management: Improper handling of authentication tokens can lead to session hijacking or unauthorized API access [S3].
Concrete Fixes
Implement Row Level Security (RLS)
For applications using Postgres-based backends like Supabase, RLS must be enabled on every table. RLS ensures that the database engine itself enforces access constraints, preventing a user from querying another user's data even if they have a valid authentication token [S5].
Automate Secret Scanning
Integrate secret scanning into the development workflow to detect and block the push of sensitive credentials like API keys or certificates [S2]. If a secret is leaked, it must be revoked and rotated immediately, as it should be considered compromised [S2].
Enforce Strict Token Practices
Follow industry standards for token security, including using secure, HTTP-only cookies for session management and ensuring tokens are sender-constrained where possible to prevent reuse by attackers [S3].
Apply General Web Security Headers
Ensure the application implements standard web security measures, such as Content Security Policy (CSP) and secure transport protocols, to mitigate common browser-based attacks [S1].
