Refresh-token rotation bug (found via Solaria smoke test):
* RefreshClaims now carries a unique random jti (UUID v4). Without it, two
refresh tokens issued in the same second (e.g. on rotation) were byte-identical
— breaking rotation, colliding on the tokenHash unique index, and making a
stolen old token indistinguishable from the new one. Every refresh token is
now unique regardless of issue time. Added a unit test asserting consecutive
tokens differ.
Code cleanup (review items):
* #15: removed unused deps tower_governor, slog, thiserror (zero refs in src/).
* #30: deleted leftover src/main.rs.restore (a stale git-error-message backup).
* #28: removed the 9 single-line-comment stub files under src/db/ (appointment,
family, health_data, lab_result, medication, profile, permission, share, user)
and their mod declarations; nothing referenced them, real logic lives in
mongodb_impl.rs/init.rs.
* #29: stripped 61 broad module-level #![allow(...)] suppressions across src/.
Fixed the surfaced warnings instead: 4 unused 'claims' extractor bindings ->
_claims; removed dead OpenFDAService.client/base_url fields + the never-called
query_drug_events method + unused HashMap/reqwest imports; applied clippy's
mechanical fixes (Ok(?) -> ?, Copy ObjectId clone, redundant closures,
useless conversions); rewrote 'if let Ok(_) = x' -> 'if x.is_ok()'. Result:
cargo build + clippy --all-targets are warning-free with no blanket allows.
Verified: fmt clean, build clean, clippy 0 warnings, 19 unit tests pass
(was 18; +1 jti-uniqueness test).
Address the four P0 security items from the project review:
* token_version validation (#1): the JWT middleware now rejects access tokens
whose token_version claim is stale (e.g. issued before a password change).
A short-TTL (30s) in-memory cache (TokenVersionCache) avoids a Mongo lookup
per request; credential changes invalidate the cache immediately on the
handling instance.
* Fail-fast config (#2): add APP_ENVIRONMENT (development|production). In
production the server refuses to boot unless JWT_SECRET and ENCRYPTION_KEY
are set to non-default values; development keeps the insecure defaults with
a warning.
* Real client IP in audit logs (#4): new client_ip middleware resolves the
originating IP (X-Forwarded-For > X-Real-IP > ConnectInfo socket) and
exposes it via a ClientIp extractor. All five hardcoded "0.0.0.0" audit
calls are replaced, and the missing PasswordChanged audit event is added to
change_password. axum::serve now uses into_make_service_with_connect_info.
* Refresh token persistence (#5): refresh tokens are now stored hashed in
MongoDB (RefreshTokenRepository) instead of an in-memory map lost on restart.
Added /api/auth/refresh (with rotation + token_version check) and
/api/auth/logout routes; register/login return a refresh_token; password
change/recovery revoke all of a user's refresh tokens. JwtService now honors
JwtConfig expiries instead of hardcoding 15min/30d, and the dead in-memory
refresh store is removed.
Also: wire up DatabaseInitializer (was never called), fix the refresh_tokens
index to tokenHash + add an expiresAt TTL index, add sha2 dep.
Rate limiting (#3) is deferred per scope; the stub remains.
Verified: cargo fmt --check clean, cargo build/clippy --all-targets clean,
18 unit tests pass (9 new). Integration tests (tests/*) still need a live
server — fixing them is tracked as P1.
BREAKING CHANGE: AuthResponse now includes a refresh_token field.
- Apply rustfmt to all Rust source files in backend/
- Fix trailing whitespace inconsistencies
- Standardize formatting across handlers, models, and services
- Improve code readability with consistent formatting
These changes are purely stylistic and do not affect functionality.
All CI checks now pass with proper formatting.
