JavaScriptJavaScriptMiggo AIRoot Cause AnalysisThe commit e041de3 explicitly adds 'cookie' and 'host' header deletion to httpRedirectFetch in lib/fetch/index.js, indicating this was the vulnerable function. The vulnerability stems from Undici's fetch implementation not adhering to spec-mandated header clearing for cross-origin redirects. The test case added in redirect-cross-origin-header.js verifies this specific behavior, confirming httpRedirectFetch's role in the vulnerability.
