- `/api/metrics` in Prometheus text format, off until `METRICS_TOKEN`
or `METRICS_TOKEN_FILE` is set (404 before, 401 without the bearer
token): requests per route group with status class and latency,
sign-in outcomes, calls to Stalwart, WOPI, translation, the plugin
proxy and OAuth, browser errors, errors today, process memory,
event-loop lag, uptime and build info. Labels come from fixed lists.
Each replica serves its own.
- `/api/health/live` answers while the process runs;
`/api/health/ready` checks the config, the shared store, writable
data dirs and Stalwart's session resource. `/api/health` and
`/api/ready` are unchanged.
- the Docker image gets a HEALTHCHECK on the live endpoint
- adds prom-client, and the OpenTelemetry packages the tracing step
loads on demand
The origin gate in the proxy only covered `/api/auth/*`. The JMAP
passthrough, `/api/settings`, `/api/wopi/launch`,
`/api/plugin-approval-status`, `/api/fetch-ical`, `/api/translate`,
`/api/caldav/discover`, `/api/calendar-agenda` and `/api/webdav` all act
with the session cookie and had no origin check. A page on a same-site
sibling origin receives SameSite=Lax cookies, so it could run arbitrary
JMAP as the signed-in user, including sharing mailboxes to a third
account.
The proxy now gates every `/api/` route except the WOPI file endpoints
the office editor calls server-to-server, and each of these handlers
checks again. The proxy also decides on the decoded path, so an escaped
spelling such as `/api/%61uth/session` no longer skips the gate.
