CVE-2026-58404 Hugo security.http.urls deny rules bypassed by alternate IPv4 encodings

Hugo is a static site generator. From v0.162.0 through v0.163.0, the default security.http.urls policy denies requests to loopback, internal, and cloud-metadata IPv4 literals, but the deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses, including...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...
