| Doc Text: |
A flaw was found in the `html/template` component of Go (golang). Pathological inputs could prematurely close an unescaped forward slash ('/'), allowing an attacker to inject arbitrary content. This could lead to Cross-Site Scripting (XSS), where malicious scripts are executed in a user's browser, potentially compromising user data or actions.
