CVE-2026-27136

Опубликовано: 22 мая 2026

CVSS3: 8.1

Описание

Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering.

A flaw was found in golang.org/x/net/html. When arbitrary HTML is parsed and then rendered, it can result in an unexpected HTML tree. This allows an attacker to bypass HTML sanitization mechanisms, leading to Cross-Site Scripting (XSS) attacks in applications. Such attacks can result in information disclosure or arbitrary code execution.

Отчет

This vulnerability in golang.org/x/net/html is rated as Important. It allows for Cross-Site Scripting (XSS) attacks by enabling an attacker to bypass HTML sanitization mechanisms when arbitrary HTML is parsed and rendered. This can lead to information disclosure or arbitrary code execution in affected applications. Exploitation typically requires user interaction, where a user processes specially crafted malicious HTML content.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
