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].
How FixVibe tests for it
FixVibe already covers this data-leak class across multiple live scan surfaces:
- Supabase RLS 暴露:
baas.supabase-rls从同源包中提取公共 Supabase URL/匿名密钥对,枚举暴露的 PostgREST 表,并执行只读匿名 SELECT 检查以确认表数据是否暴露。

- 存储库 RLS 差距:
baas.supabase-rls审查授权的 Supabase 存储库 SQL 迁移,用于在没有匹配的 Supabase 迁移的情况下创建的公共表。

- Supabase 存储态势:
baas.supabase-rls审查公共存储桶元数据和匿名列表曝光,而无需上传或更改客户数据。

- 秘密和浏览器状态:
baas.supabase-rls、Supabase 和 Supabase 标记泄漏的客户端凭据、缺少浏览器强化标头以及弱 auth-cookie 标记。

- 门控访问控制探针:当客户启用主动扫描并验证域所有权时,
baas.supabase-rls和 Supabase 测试发现 IDOR/BOLA 式跨资源和跨租户数据暴露的路线。 - Repo RLS gaps:
