CVE-2019-14809 is a critical authorization bypass vulnerability affecting Go versions before 1.11.13 and 1.12.8, specifically within the net/url package. It arises from mishandling malformed hosts in URLs, where a crafted URL can lead to an incorrect hostname interpretation, potentially allowing an attacker to bypass authorization mechanisms in applications using the affected Go versions. With a CVSS score of 9.8 (Critical), this vulnerability is easily exploitable over the network with low attack complexity, posing a high risk to confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, organizations using affected Go versions should prioritize patching to mitigate this severe risk.
