Vulnerabilities 4
-
Medium 6.1
Invoking incorrect handling of character references in DOCTYPE nodes in golang.org/x/net/html
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.

Invoking duplicate attributes can cause XSS in golang.org/x/net/html
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.
-
Medium 6.1
Invoking incorrect handling of HTML elements in foreign content in golang.org/x/net/html
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.
