About this tag
The cve-2026-25681 tag covers a medium-severity cross-site scripting flaw in the Go x/net/html package before version v0.55.0. Microsoft’s Security Update Guide tracks the issue after the Go project’s May 2026 security update. Malformed DOCTYPE character references can create an unsafe rendered HTML tree, affecting Go-built services, agents, portals, scanners, dashboards, and other internal tools hosted on Windows. This archive focuses on understanding the vulnerability, identifying applications that depend on the affected package, and applying the updated Go dependency. The issue is an application and library security concern rather than a Windows kernel flaw, browser zero-day, or conventional Patch Tuesday headline.
