The right-most IP should be extracted as it represents the nearest trusted proxy, mitigating these spoofing risks. +**Prevention:** In rate-limiting and observability middlewares, ensure the right-most value (`xff.split(",")[-1].strip()`) is extracted when relying on the `X-Forwarded-For` header to guarantee that the IP address corresponds to the nearest, authenticated hop. +## 2025-02-28 - Snowflake DSN Authenticator SSRF +**Vulnerability:** The Snowflake DSN parser accepted arbitrary URLs in the `authenticator` query parameter without validation, leading to potential SSRF (Server-Side Request Forgery).

This allows an attacker to exploit the algorithm mechanism, forging a JWT token by treating the public JWKS key as an HMAC secret if the JWT decoder allows the `HS256` header algorithm. +**Learning:** You must not blindly trust the JWT token header algorithm (`alg`). You must explicitly supply a whitelist of acceptable algorithms to your JWT library AND ensure that public key verification configurations explicitly filter out symmetric algorithm families (`HS*`). +**Prevention:** Filter out `HS` algorithms when reading allowed configuration algorithms, and explicitly block them in allowlists passed to JWT decoders when dealing with RS256/ES256 public keys. + +## 2026-06-22 - Missing Rate Limiting on Token Revocation Endpoint +**Vulnerability:** The `/api/auth/logout` token revocation endpoint lacked its intended tighter rate limit because `_revoke_rate_limit_policy` in `backend/app/main.py` used the stale route prefix `"/api/auth/revoke"` instead of `"/api/auth/logout"`. +**Learning:** Any endpoint that interacts with caching systems or performs authentication state mutations must have strict rate limiting to prevent resource exhaustion and abuse. Route-prefix policies must match the actual `APIRouter` path exactly. +**Prevention:** Always verify that sensitive endpoint rate-limit prefixes match the actual route definitions, and keep app-wiring regression tests for those policies. +## 2024-05 - [CRITICAL] Authentication Bypass via X-Dev-User Leftover Mitigation +**Vulnerability:** Leftover logic defining an `X-Dev-User` bypass vector existed partially in the backend CORS allowed headers and heavily in the frontend via localStorage and request headers. +**Learning:** Even after backend vulnerability logic is removed (e.g. `try_get_subject_for_rate_limit` fallback logic removed), residual CORS configurations (`backend/app/main.py`) or client-side storage & transmission (`frontend/src/api.ts` and `frontend/src/App.tsx`) might still mistakenly use and expose development bypass tokens. +**Prevention:** When removing an auth-bypass test vector, conduct a full-stack search (e.g., `grep -rn "X-Dev-User" .`) to ensure the entire trace, including frontend localStorage keys, UI toggles, and backend CORS configuration, is cleanly removed. + +## 2026-06-23 - OIDC JWKS 갱신 관련 서비스 거부(DoS) 취약점 +**Vulnerability:** JWT 인증을 처리하는 `_get_jwks` 함수에서, 알 수 없는 `kid`를 가진 토큰이 유입될 때마다 `force_refresh=True`가 호출되어 OIDC 엔드포인트(JWKS)로 외부 HTTP 갱신 요청을 즉시 보냅니다. 공격자가 고의로 무작위 `kid`를 포함한 토큰을 대량으로 보내면, 서버는 불필요하게 잦은 외부 요청을 수행하게 되어 스레드 고갈이나 외부 OIDC 제공자로부터 Rate Limit 제한을 받는 DoS(서비스 거부) 공격에 취약해집니다. +**Learning:** 서드파티 OIDC 제공자나 외부 API를 통해 공개키/설정을 동적으로 가져오는(fetch) 패턴에서는, 인증에 실패하거나 캐시 미스(Cache Miss)가 발생하는 경우에도 외부 요청을 제한할 수 있는 디바운싱(Debouncing), Rate Limiting, 그리고 동시 갱신 직렬화가 필요합니다. +**Prevention:** 강제 캐시 갱신(`force_refresh`) 요청이 들어오더라도 `OIDC_JWKS_MIN_REFRESH_INTERVAL` 변수와 JWKS 갱신 lock을 사용하여 최소 갱신 간격을 보장하고 concurrent bad `kid` 요청이 외부 호출을 병렬 증폭하지 못하게 합니다. + +## 2024-06-25 - Fix SSRF validation rejecting Okta root domain +**Vulnerability:** A logic bug in `_parse_snowflake_dsn` incorrectly rejected authenticators using Okta root domains `okta.com` or `oktapreview.com` because it only checked `endswith(".okta.com")`, functioning as a DoS for legitimate configurations. +**Learning:** `endswith(".okta.com")` does not match `okta.com` due to the leading dot. This caused valid configurations to be rejected. +**Prevention:** Always explicitly allow the exact root domain when performing suffix checks that require a subdomain delimiter. +## 2026-06-22 - Token Revocation Cache and Project Members Access +**Learning:** The token revocation mechanism used an in-memory dictionary `_revoked_token_jtis` that doesn't persist across application restarts. This could allow revoked tokens to become valid again after a service restart until their natural expiration. Also, the `list_project_members` endpoint did not properly check authorization, potentially allowing low-privilege users (e.g. viewers) to enumerate all project members. +**Action:** Always implement persistent storage (e.g. database or Redis) for revoked tokens to ensure revocation survives application restarts. Also, ensure appropriate role-based access controls are strictly applied for viewing members in project spaces. + +## 2026-06-22 - IDOR in Project Members List +**Learning:** The `/api/projects/{project_space_uuid}/members` endpoint exposed the full list of members and their roles to any user with `viewer` access. This excessive visibility could facilitate enumeration and social engineering attacks. +**Action:** Implemented stricter role-based access control (RBAC) on the endpoint to require a minimum `editor` role to view project members, mitigating the IDOR risk. +## 2024-06-30 - JWT Algorithm Confusion + +**Vulnerability:** The application was susceptible to JWT algorithm confusion. It decoded JWTs without validating that the algorithm provided in the token header (`alg`) matched the key type (`kty`) of the JSON Web Key (JWK) fetched from the provider. +**Learning:** Even when using a fixed whitelist of allowed algorithms (`RS256`), an attacker can craft a token with an `RS256` header, but if the provider somehow exposes both symmetric and asymmetric keys, or if the library misinterprets the key format, it could lead to improper validation. More importantly, explicitly enforcing `kty` to `alg` alignment prevents a wide class of downgrade/confusion attacks before `jwt.decode` is even invoked. +**Prevention:** Always validate that `kty == 'RSA'` requires `alg` starting with `RS` or `PS`, and `kty == 'EC'` requires `alg` starting with `ES`. Never rely solely on the `alg` header or the presence of a key identifier (`kid`) without checking the key material's intended type. + +## 2026-06-26 - Password Leak in Database Introspection Exceptions +**Vulnerability:** Database driver exceptions can echo DSN fragments, query parameters, or assignment-style secrets after connection failures, leaking plaintext passwords through snapshot error messages and queue logs. +**Learning:** Redacting only the literal DSN is not enough. Error messages may contain decoded, percent-encoded, query-string, or `password=`/`api_key=` style forms of the same secret. +**Prevention:** Sanitize snapshot job errors before persisting or re-raising them, and raise sanitized exceptions with `from None` so Python exception chaining does not reattach the original secret-bearing exception. + +## 2024-07-07 - URL parsing failure leaks credentials for schemes with underscores +**Vulnerability:** Python's `urllib.parse.urlsplit` fails to parse schemas that contain an underscore (e.g., `snowflake_invalid://`). This moves the credentials into the path instead of recognizing them. In `backend/app/dsn_redaction.py`, this caused the application to fail to find and redact the credentials inside error messages for DSNs with non-standard underscore schemes, leading to a risk of secrets exposure. +**Learning:** Python's URL parsers strictly adhere to RFC schemes. Any application that uses `urlsplit` or `urlparse` to handle arbitrary strings like custom database DSNs that might have non-standard characters like `_` needs to preprocess them or handle empty schemes properly. +**Prevention:** If extracting data from a URI, temporarily overwrite non-compliant schemes to a standard one (e.g., `http://`) before using standard URL parsing libraries. diff --git a/AGENTS.md b/AGENTS.md deleted file mode 100644 index ec76a127..00000000 --- a/AGENTS.md +++ /dev/null @@ -1,101 +0,0 @@ -# AGENTS.md - -Cross-agent conventions for this repo (`pg-erd-cloud`), readable by any coding -agent (Claude, Codex, Cursor, opencode, …).

The app's own PostgreSQL stores metadata: users, project spaces/members, encrypted DB connections, schema snapshots, job queue, diagram views, annotations, share links, API keys (`app/models.py`). -- **frontend/** — React 19 + TypeScript + Vite SPA. The ERD canvas is built on `@xyflow/react` (React Flow). Core ERD logic lives in `src/erd/` (snapshot→graph conversion, cardinality, FK auto-inference, DBML/Mermaid/SQL export); modal dialogs in `src/components/modals/`. Tests use Vitest + Testing Library (plus fast-check fuzz tests). -- **deploy/traefik/** — Traefik dynamic config used by `compose.prod.yaml`. - -### Backend layout (backend/app/) - -- `api/` — FastAPI routers (projects, connections, snapshots, share, diagram_views, annotations, api_keys, auth_routes, me), all mounted in `main.py` under `/api`. -- `jobs/` — Postgres-backed job queue (`JobQueue` table). Reverse engineering never blocks the request path: the API enqueues a `snapshot` job, and an in-process worker task (started in the FastAPI lifespan in `main.py`) claims and executes it. Optional Valkey/Redis (`valkey_queue.py`) is only a wake-up signal; Postgres remains the source of truth. -- `pg_introspect/` — pg_catalog-based introspection of the *target* PostgreSQL: schemas/tables/columns, PK/FK/UNIQUE/CHECK, indexes. Index access methods are discovered dynamically from `pg_am`/`pg_class.relam` and index DDL is preserved losslessly via `pg_get_indexdef()` — do not hardcode an index-type list (project principle, see README). Also synthesizes safe `example_value` column hints from name/type metadata only (never samples real table data). -- `snowflake_introspect/` — optional Snowflake reverse engineering (INFORMATION_SCHEMA; requires the `snowflake` extra). -- `ddl/` — forward engineering: snapshot → DDL export with dialect mapping, migration SQL, migration-safety checks. -- `diff/` — snapshot-to-snapshot schema diff. -- `spec/` — reversing-spec generation, naming lint, data dictionary, relationship inference, LLM integration. -- Cross-cutting: `auth.py` (OIDC/Casdoor JWT verification when `OIDC_ISSUER` is set, plus API keys and token revocation), `csrf.py`, `rate_limit.py` (in-memory fixed-window; global `/api/*` limit plus a stricter separate limit for public `/api/share/*`), `security_headers.py`, `observability.py` (JSON request logs + Prometheus metrics — see docs/observability.md), `sanitize.py`/`dsn_redaction.py`, `settings.py` (pydantic-settings; env vars are documented in `.env.example`). - -### Data flow - -1. A user registers a target-DB connection; the DSN is encrypted with `APP_SECRET` before being stored in the app DB. -2. Requesting a snapshot enqueues a job; the background worker connects to the target DB, introspects it, and stores a JSON snapshot (`SchemaSnapshot` + `SchemaSnapshotData`). -3. The frontend fetches snapshots via `/api/*` and renders the ERD; all exports (DDL, diff/migration SQL, reversing spec, DBML/Mermaid) are derived from the stored snapshot, not from live DB access. -4. Share links expose read-only snapshot/export routes under `/api/share/{share_uuid}/...` with a tighter rate limit, and sensitive fields (schema comments, example values) are redacted from publicly shared payloads. - -### Dev vs prod compose - -- `compose.yaml` (dev): postgres + backend + frontend. Bind mounts and hot reload; backend on 127.0.0.1:8000, frontend on 127.0.0.1:5173; `APP_SECRET` comes from `.env`; CORS allows http://localhost:5173. -- `compose.prod.yaml`: adds a Traefik edge router on :8080 that routes `/api/*` and `/healthz` to the backend and everything else to a static frontend (`frontend/Dockerfile.prod` builds `dist/` served by `serve-static.mjs`). No bind mounts or reload; `APP_SECRET` is injected as a Docker secret file (`APP_SECRET_FILE=/run/secrets/app_secret`); only Traefik is published. Traefik also applies security-headers middleware (`deploy/traefik/dynamic.yaml`). -- Both compose files run `alembic upgrade head` before starting the backend, so migrations must always be committed alongside model changes. - -## Conventions and gotchas - -- `APP_SECRET` is the encryption key for stored DSNs — changing it breaks decryption of existing data. Prefer `APP_SECRET_FILE` injection in production. -- Never commit `.env`, `secrets/`, credentials, or DSNs. Treat DSNs and generated schema metadata as sensitive (SECURITY.md, docs/api-security-checklist.md). -- Backend code is strictly typed: mypy runs with `disallow_untyped_defs` (see `[tool.mypy]` in backend/pyproject.toml). Public defs need docstrings — interrogate is configured with `fail-under = 100` in setup.cfg and `tests/test_docstrings.py` enforces it for checked modules. -- Long-running work (introspection of target DBs) goes through the job queue, never synchronously in a request handler. -- Middleware registration order in `app/main.py` is deliberate (security headers registered last so they wrap everything, including 429s and CORS preflight) — read the comments there before reordering. -- Do not use nested `${VAR:-${OTHER:-default}}` expressions in compose files; podman-compose mishandles them (noted inline in compose.yaml). -- Supply-chain pinning is enforced (OpenSSF Scorecard): Docker images are pinned by digest, GitHub Actions by commit SHA, and pip installs by `--require-hashes`. Preserve pinning when adding or updating any of these. -- CI (`.github/workflows/ci.yml`) runs backend mypy + pytest (Python 3.10, hash-locked deps) and frontend typecheck + vitest + production build (Node 26). CodeQL, Scorecard, and dependency-review workflows also run. -- User-visible frontend changes are recorded in CHANGELOG.md (Korean) and frontend/CHANGELOG.md. -- Add or update tests when changing behavior; prefer small, focused PRs (CONTRIBUTING.md). diff --git a/backend/alembic/versions/0003_revoked_token.py b/backend/alembic/versions/0003_revoked_token.py index 88296542..b7bcce29 100644 --- a/backend/alembic/versions/0003_revoked_token.py +++ b/backend/alembic/versions/0003_revoked_token.py @@ -1,7 +1,7 @@ """revoked_token Revision ID: 0003 -Revises: 0002_auth_share +Revises: 0002 Create Date: 2026-06-22 10:00:00.000000 """ @@ -12,7 +12,7 @@ # revision identifiers, used by Alembic. revision = "0003" -down_revision = "0002_auth_share" +down_revision = "0002" branch_labels = None depends_on = None diff --git a/backend/alembic/versions/0004_merge_heads.py b/backend/alembic/versions/0004_merge_heads.py deleted file mode 100644 index 14a457f9..00000000 --- a/backend/alembic/versions/0004_merge_heads.py +++ /dev/null @@ -1,28 +0,0 @@ -"""merge revoked_token and validate_project_space_fk into a single head -
