check / check (push) Superseded by a newer commit; never tested
The receiver had no inbound authentication of any kind: /webhook/{uuid}
was mounted behind a rate limiter alone, so the only thing protecting an
entrypoint was the secrecy of a v4 UUID in a URL path. Inbound headers are
forwarded almost verbatim to the target, so anyone who learned the URL
also chose the headers the downstream service received.
Adds an optional per-entrypoint secret with two schemes: github
(X-Hub-Signature-256, HMAC-SHA256 hex over the raw body) and gitlab
(X-Gitlab-Token, a plain shared token). Comparison is constant-time, the
HMAC is computed over the raw body before any parsing, and rejection
happens before persistence -- an unauthenticated request creates no event
row. An entrypoint with no secret behaves exactly as before, including
every row that predates this change.
The scheme's credential header is stripped from the header map before it
is marshalled into Event.Headers, so the GitLab token reaches neither the
event store nor any delivery target. SchemeInfo.HeaderIsDigest defaults to
false meaning strip, so a scheme added later is protected unless its
header is positively declared a digest.
Unifies user-visible copy on "Webhook" (routes and URLs unchanged), drops
the placeholder Profile settings section, and adds a copy-to-clipboard
affordance for the entrypoint URL as progressive enhancement — the button
stays hidden unless both the target element and the Clipboard API resolve,
so no dead control appears without JavaScript and the URL stays selectable.
Retention copy now matches what the code does: deletion is permanent, 0
retains forever, and a blank field means the default on create or the
current value on edit. The permanent-deletion sentence is suppressed for a
retain-forever webhook, which the reaper exempts before computing a cutoff.
Template tests gained a render-completed assertion. Without it, a page that
aborted mid-render still satisfied assertions matching the already-flushed
prefix, because renderTemplate streams to the ResponseWriter (#123).
