lever: untrusted hostname "${parsed.hostname}" — must be one
Error message
lever: untrusted hostname "${parsed.hostname}" — must be one of: ${[...ALLOWED_LEVER_HOSTS].join(', ')} What it means
Third guard in assertLeverUrl: parsed.hostname must be in ALLOWED_LEVER_HOSTS ({'api.lever.co','api.eu.lever.co'}). The message lists both permitted hosts. This is the SSRF allowlist — it stops a config from directing the fetch at an arbitrary host.

Solutions
- Point api: at https://api.lever.co/v0/postings/<slug> (or api.eu.lever.co for EU boards).
- If using careers_url auto-detection, confirm it derives an api.* host; otherwise set api: explicitly.
- If Lever adds a new regional API host, extend ALLOWED_LEVER_HOSTS after verifying it is official.
Example fix
// before api: https://jobs.lever.co/acme // after api: https://api.lever.co/v0/postings/acme
Defensive patterns
Strategy: validation
Validate before calling
import { URL } from 'node:url';
const ALLOWED = new Set(['api.lever.co', 'api.eu.lever.co']);
export function isTrustedLeverHost(value) {
try { return ALLOWED.has(new URL(value).hostname); } catch { return false; }
} Type guard
/** @param {string} url */
function isLeverApiHost(url) {
try { return new URL(url).hostname === 'api.lever.co' || new URL(url).hostname === 'api.eu.lever.co'; } catch { return false; }
} Try / catch
try {
assertLeverUrl(url);
} catch (err) {
if (err.message.includes('untrusted hostname')) console.error(`[security] ${err.message}`);
throw err;
} Prevention
- Use api.lever.co (or api.eu.lever.co for EU boards) — never the jobs.lever.co careers host — for the api: field.
- Treat an untrusted-hostname error as a security signal, not a typo to silence.
- Extend ALLOWED_LEVER_HOSTS only after verifying a new host is an official Lever API endpoint.
When it happens
Trigger: An HTTPS URL whose hostname is neither api.lever.co nor api.eu.lever.co — e.g. jobs.lever.co (the human-facing host, not the API), www.lever.co, api.lever.co.evil.com, or a corporate domain. The bad hostname is interpolated into the message.
Common situations: Config used the careers page host (jobs.lever.co) instead of the API host; a regional EU endpoint was spelled wrong; the entry points at a corporate front-end rather than the postings API.
