Summary

@asymmetric-effort/specifyjs: `data:` URI allowed without size restriction

Details

Finding

Location: core/src/shared/secure-fetch.ts:33-35

data: URIs were allowed without any restriction. While data: URIs don't make network requests, they can be used for memory exhaustion via very large data URIs.

Status

Fixed in v0.2.136 — data: URIs are now limited to 1MB. URIs exceeding this limit throw an error.
