Merge Risk: 🔵 Low · up to The PR tightens passkey origin validation and logging, but ASCII-only host normalization can reject legitimate passkey ceremonies for internationalized domains. It is mergeable with explicit owner awareness or follow-up for this bounded compatibility risk. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

to convert non-bracketed hosts with idn_to_ascii(), returning null when
conversion fails, before comparing origins; retain strtolower() for bracketed
IPv6 hosts. Add regression coverage for both uppercase and lowercase
internationalized host inputs.

Canonicalize internationalized hosts before comparison.
strtolower() is ASCII-only, so https://BÜCHER.example does not normalize to the browser’s ASCII origin. Convert non-bracketed hosts with idn_to_ascii() and return null on failure. Keep strtolower() for bracketed IPv6 hosts. Add uppercase and lowercase IDN regression cases.

That PR put
AuthenticatorResponseVerificationExceptionin$dontReportbut only logged origin failures. The same exception covers signature mismatches, failed user verification and clone detection, so those were disappearing silently. Everything gets logged now.The log had the wrong origin in it too. It recorded the
Originheader, but the library compares the origin insideclientDataJSON- the two disagreeing is the case you actually want to debug. Both are in there now.The middleware trusted the
Originheader on its own. It's checked against the host the request was routed to now, so a forged header can't whitelist an origin for some other host. That leaves the port as the only part a caller can still influence, andPASSKEYS_STRICT_ORIGIN=trueturns that off completely.Smaller things: origins are lowercased before comparing,
PASSKEYS_RELYING_PARTY_IDtakes a bare domain or a full URL, non-JSON requests fall through to the normal error page instead of getting a JSON body back, andweb-auth/webauthn-libis required explicitly since we import from it.Unit tests for
PasskeyOriginandAllowPasskeyOrigin.
