Affected packages

• npm @asymmetric-effort/specifyjs: < 0.2.136 → fixed in 0.2.136

Description

Finding Location: `core/src/shared/secure-fetch.ts` `assertSecureUrl` validated only the initial request URL. The `fetch()` API follows redirects by default (up to 20 hops). A request to a valid `https://` URL could redirect to `http://internal-service/` or other unvalidated destinations. Status Fixed in v0.2.136 — `secureFetch` now defaults to `redirect: 'error'` which rejects any redirect. Callers can override with `{ redirect: 'follow' }` if they trust the target.
