getonbrd: untrusted hostname "${parsed.hostname}" — must be

Error message

getonbrd: untrusted hostname "${parsed.hostname}" — must be ${TRUSTED_HOST}

What it means

getonbrd.mjs throws this in assertGetonbrdUrl() when the URL is valid HTTPS but its hostname is not TRUSTED_HOST ('www.getonbrd.com'). It is the host-allowlist half of the SSRF guard; with redirect:'error' it pins every Get on Board request to www.getonbrd.com. A live throw means FEED_BASE's hostname drifted off the trusted host.

Solutions

  1. Restore FEED_BASE to https://www.getonbrd.com/api/v0/categories/programming/jobs.
  2. If a different host is genuinely required, update TRUSTED_HOST to match in the same change and record the reason.
  3. Keep tests that hit this branch asserting the throw rather than changing the input.

Example fix

// before
const FEED_BASE = 'https://getonbrd-cdn.example.com/api/v0/categories/programming/jobs';
const TRUSTED_HOST = 'www.getonbrd.com'; // mismatch

// after
const FEED_BASE = 'https://www.getonbrd.com/api/v0/categories/programming/jobs';
const TRUSTED_HOST = 'www.getonbrd.com';
Defensive patterns

Strategy: validation

Validate before calling

// Startup invariant: the Get on Board feed host must equal TRUSTED_HOST.
function checkGetonbrdHost() {
  const u = new URL('https://www.getonbrd.com/api/v0/categories/programming/jobs');
  if (u.hostname !== 'www.getonbrd.com') throw new Error('getonbrd host drift');
}

Prevention

When it happens

Trigger: FEED_BASE was pointed at a mirror/CNAME (e.g. 'https://getonbrd-mirror.example.com/...') without updating TRUSTED_HOST; a test calls assertGetonbrdUrl('https://evil.com/...'); the constant and the trusted host were edited out of sync.

Common situations: Contributor adds a regional mirror but edits only one symbol; a security test throws foreign hosts at the guard; an env override redirected the provider.
