Miggo AIRoot Cause Analysis
The vulnerability stems from the absence of a domain validation check during redirects in the fetch implementation. The fix introduced the 'isDomainOrSubdomain' check to strip sensitive headers when redirecting to untrusted domains. The vulnerable code existed in the redirect handling portion of the fetch function, which previously forwarded headers without this security check. The commit diff and CVE description confirm the lack of origin validation was the root cause.
