## Finding
**Location**: `core/src/shared/secure-fetch.ts:52-54`
The localhost exception allowed `localhost` and `127.0.0.1` but did not cover `0.0.0.0`, `[::1]` (IPv6 localhost), or the full `127.0.0.0/8` loopback range.
## Status
**Fixed in v0.2.136** — Localhost detection now covers `localhost`, `127.0.0.1`, `[::1]`, `0.0.0.0`, and the full `127.x.x.x` range.
