The 8 multi-tenant failure modes that will leak customer data (and how we test against them)

Hey founders and devs, A multi-tenant data leak is the fastest way to kill a B2B SaaS company's reputation. Yet, most teams rely on standard unit tests that only verify happy paths rather than actively trying to breach tenant boundaries. Before launching our B2B stack, we wrote an 8-point adversarial test runner to stress-test our Postgres RLS and Next.js backend setup. Here are the 8 failure modes every multi-tenant SaaS needs to test for: Cross-tenant reads/writes via direct ID

痛点：多租户 B2B SaaS 缺乏系统性的租户隔离对抗测试，常规单元测试只覆盖正常路径，容易漏掉跨租户数据泄露。

目标用户：使用 Postgres RLS、Next.js 和 Stripe 的 B2B SaaS 独立开发者、技术创始人及小型工程团队。

变现：开源 CLI + 付费云仪表盘/CI 集成：按团队席位或私有仓库数量订阅，提供合规报告、定时扫描、Slack 告警和安全审计服务。

MVP：做一个 2 周可交付的 CLI：连接测试 Postgres，播种两个租户，自动运行 8 类对抗测试（IDOR、JWT 过期、RLS 视图绕过、Webhook 重放等），输出 JSON/HTML 报告，并提供 GitHub Action 模板。

竞品：pgTAP、Snyk、Semgrep、OWASP ZAP、StackHawk

摘要：帖子列出 8 种多租户数据泄露失败模式，作者为 Postgres RLS + Next.js 后端写了对抗性测试 runner，并指出多数团队只做 happy path 单测。虽然没有直接付费或收入证据，但多租户隔离测试是 B2B SaaS 的真实高频痛点，适合独立开发者做轻量 CLI/CI 工具。建议从开源测试 runner 切入，再通过云报告和团队协作订阅变现。
