Html Template
Monthly
Cross-site scripting (XSS) vulnerability in Go's html/template library allows attackers to bypass URL escaping in meta tag content attributes by inserting ASCII whitespaces around the equals sign, enabling injection of malicious scripts into web applications. Affects Go 1.25.x before 1.25.10 and 1.26.x before 1.26.3. This is a regression from CVE-2026-27142 where the fix was incomplete, and exploitation requires user interaction (UI:R) but operates across security boundaries (S:C).
