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"}
