ClosesDraco-Lunaris/Linux-Patch-Manager#10
The browser WebSocket endpoint at GET /api/v1/ws/jobs previously
authenticated solely via a single-use, 60-second ticket passed as a query
parameter. A leaked ticket (browser history, Referer, proxy logs, support
bundles) could be redeemed from any origin, enabling Cross-Site WebSocket
Hijacking (CSWSH).
This change adds a second gate: the Origin header must match an explicit
allowlist. The check runs BEFORE ticket validation so that rejected
cross-origin probes do not consume the legitimate users ticket.
Changes:
- pm-core: new security.allowed_origins config field; default derived
from sso_callback_url; startup warning if both are unparseable
- pm-web: ws_handler extracts HeaderMap and calls check_origin first;
returns 403 on missing/malformed/disallowed origins
- config: documented allowed_origins key in config.example.toml
- docs: security-review.md section 1.4 (WebSocket Origin Allowlist)
- tests: 40 unit tests (7 pm-core, 33 pm-web)
BUG-10: PostgreSQL inet type includes CIDR suffix (/32) when cast to text,
causing malformed agent URLs like https://127.0.0.1/32:12443.
Fixed by using host(ip_address)::text in all SQL queries across
pm-worker and pm-web modules, and adding a Rust-side safety
strip of CIDR notation in pm-agent-client.
Files changed:
- crates/pm-agent-client/src/client.rs: strip CIDR suffix from IP
- crates/pm-worker/src/health_poller.rs: host(ip_address)::text
- crates/pm-worker/src/patch_poller.rs: host(ip_address)::text
- crates/pm-worker/src/refresh_listener.rs: host(ip_address)::text
- crates/pm-worker/src/job_executor.rs: host(ip_address)::text (2 places)
- crates/pm-worker/src/ws_relay.rs: host(h.ip_address)::text
- crates/pm-web/src/routes/discovery.rs: host(ip_address)::text (2 places)
- crates/pm-web/src/routes/hosts.rs: host(ip_address)::text (3 places)
- docs/linux_patch_api_research.md: added research notes
BUG-6: Add TLS support via axum-server + rustls
- Added axum-server with tls-rustls feature to workspace and pm-web
- pm-web now serves HTTPS when TLS certs exist, falls back to HTTP with warning
- setup.sh generates self-signed ECDSA P-256 TLS cert with SANs
- Config already had web_tls_cert_path/web_tls_key_path fields
BUG-7: Fix audit chain integrity errors
- Migration 005 now TRUNCATEs audit_log after adding prev_hash column
- Existing rows had broken hash chains (inserted before prev_hash existed)
BUG-8: Disable WatchdogSec in patch-manager-web.service
- pm-web does not implement sd_notify, causing systemd to kill the service
BUG-9: Disable WatchdogSec in patch-manager-worker.service
- Same issue as BUG-8, worker does not implement sd_notify
Previous fixes (BUG-1 through BUG-5) also included:
- setup.sh: PostgreSQL 15+ schema GRANTs
- Axum route syntax :param → {param} (19 routes)
- DbUser struct role: String → UserRole enum mapping
- UserRole/AuthProvider Display trait implementations
- Seed admin password hash (Argon2id)
