CVE-2015-5739 describes a critical HTTP request smuggling vulnerability in the net/http library of Go before version 1.4.3, affecting products like Fedora and Red Hat. The flaw stems from improper parsing of HTTP header keys, allowing attackers to substitute spaces for hyphens (e.g., "Content Length" instead of "Content-Length"). With a CVSS score of 9.8 (Critical), this vulnerability is easily exploitable over the network with no user interaction, leading to high impacts on confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, publicly available exploit code, or significant community discussion or media coverage.
