When you send a request with the Authorization header to one domain, and the response asks to redirect to a different domain, Deno'sfetch() redirect handling creates a follow-up redirect request that keeps the original Authorization header, leaking its content to that second domain. This vulnerability is fixed in 2.1.2.\n\ud83d\udccf Published: 2025-01-06T22:26:40.723Z\n\ud83d\udccf Modified: 2025-01-06T22:26:40.723Z\n\ud83d\udd17 References:\n1. https://github.com/denoland/deno/security/advisories/GHSA-f27p-cmv8-xhm6", "creation_timestamp": "2025-01-06T22:36:55.000000Z"}, {"uuid": "9467daa2-9ae2-4424-a574-3bf726dd2c71", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2025-21620", "type": "seen", "source": "https://t.me/cvedetector/14425", "content": "{\n  \"Source\": \"CVE FEED\",\n  \"Title\": \"CVE-2025-21620 - Deno Authorization Header Leakage\", \n  \"Content\": \"CVE ID : CVE-2025-21620 \nPublished : Jan. 6, 2025, 11:15 p.m. | 42\u00a0minutes ago \nDescription : Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults.
