CVE-2026-84394

fast-uri accepts a host that contains an unbalanced or misplaced authority bracket without reporting an error. A host that starts with an opening bracket but does not end with a closing bracket is neither validated as an IP literal nor canonicalized as a domain name, so parse returns it as the ho...

CVE-2026-84394

A flaw was found in fast-uri. The library incorrectly processes Uniform Resource Identifier URI hosts containing unbalanced brackets, leading to a discrepancy in how the host is parsed by fast-uri compared to other HTTP clients. This host confusion can allow an attacker to bypass security policie...
