Rapidly developed SaaS applications often suffer from critical security oversights. This research explores how leaked secrets and broken access controls, such as missing Row Level Security (RLS), create high-impact vulnerabilities in modern web stacks.

CWE-284CWE-798CWE-668

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 從同源包中提取公共 Supabase URL/匿名金鑰對,枚舉暴露的 PostgREST 表,並執行只讀匿名表 SELECT 是否檢查數據。

  • 門控存取控制探針:當客戶啟用主動掃描並驗證網域所有權時,baas.supabase-rls 和 Supabase 測試發現 IDOR/BOLA 式跨資源和跨租戶資料暴露的路線。
  • Repo RLS gaps: repo.supabase.missing-rls reviews authorized GitHub repository SQL migrations for public tables that are created without a matching ALTER TABLE ... ENABLE ROW LEVEL SECURITY migration.
  • Supabase storage posture: baas.supabase-security-checklist-backfill reviews public Storage bucket metadata and anonymous listing exposure without uploading or mutating customer data.
  • Secrets and browser posture: secrets.js-bundle-sweep, headers.security-headers, and headers.cookie-attributes flag leaked client-side credentials, missing browser hardening headers, and weak auth-cookie flags.
  • Gated access-control probes: when the customer enables active scans and domain ownership is verified, active.idor-walking and active.tenant-isolation test discovered routes for IDOR/BOLA-style cross-resource and cross-tenant data exposure.
