Changes made: - Added `ADMIN_USERNAME` and `ADMIN_PASSWORD` requirements to the environment schema (`env.ts`) using Zod validation. - Replaced the hardcoded credentials in `admin-auth.ts` with values sourced securely from environment variables, while maintaining existing API exports. - Added corresponding placeholders to `.env.example`. - Updated GitHub Actions CI workflow (`ci.yml`) to inject placeholder variables, preventing pipeline build failures. - Documented the critical learning in `.jules/sentinel.md` regarding refactoring constraints and CI pipeline coordination. --- .github/workflows/ci.yml | 2 ++ .jules/sentinel.md | 4 ++++ packages/web/.env.example | 4 ++++ packages/web/src/lib/server/admin-auth.ts | 4 ++-- packages/web/src/lib/server/env.ts | 2 ++ 5 files changed, 14 insertions(+), 2 deletions(-) create mode 100644 .jules/sentinel.md diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index cc24903..ce0c16f 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -26,3 +26,5 @@ jobs: JWT_SECRET: "ci-placeholder-jwt-secret-min-32-chars" DATABASE_URL: "postgresql://placeholder:placeholder@localhost:5432/placeholder" DIRECT_URL: "postgresql://placeholder:placeholder@localhost:5432/placeholder" + ADMIN_USERNAME: "ci-admin" + ADMIN_PASSWORD: "ci-placeholder-password" diff --git a/.jules/sentinel.md b/.jules/sentinel.md new file mode 100644 index 0000000..68f8091 --- /dev/null +++ b/.jules/sentinel.md @@ -0,0 +1,4 @@ +## 2024-06-01 - Hardcoded Credentials in Server Routes +**Vulnerability:** Hardcoded `ADMIN_USERNAME` and `ADMIN_PASSWORD` were directly embedded in `packages/web/src/lib/server/admin-auth.ts`, exposing administrative credentials in source code. +**Learning:** When migrating hardcoded secrets to environment variables to fix the vulnerability, you must preserve existing module API boundaries (e.g., keeping `export const ADMIN_PASSWORD = env.ADMIN_PASSWORD`) to avoid inadvertently breaking dependent modules that import these variables. Additionally, when defining new required environment variables like `ADMIN_USERNAME` and `ADMIN_PASSWORD`, remember to add corresponding placeholder values to CI pipelines (`ci.yml`) to ensure builds don't fail due to missing variables. +**Prevention:** Always use environment variables (`env.ts` with `zod` validation and `min` length requirements) for sensitive values.
