[ Description ]Official description
go-chi chi 5.2.2 through 5.5.0 contains an open redirect vulnerability in the RedirectSlashes middleware that allows attackers to redirect victims to external hosts by embedding tab characters in request paths. Attackers can craft links with a URL-encoded tab, which browsers strip from the 301 Location header and resolve as a protocol-relative URL, bypassing the fix for CVE-2025-69725.
