no-interpolation-in-tag
no-interpolation-in-tag
Detected template variable interpolation in an HTML tag. This is potentially vulnerable to cross-site scripting (XSS) attacks because a malicious actor has control over HTML but without the need to use escaped characters. Use explicit tags instead.
Likelihood: LOW
Confidence: LOW
CWE:
- CWE-79: Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’)
OWASP:
- A07:2017 - Cross-Site Scripting (XSS)

no-interpolation-js-template-string
no-interpolation-js-template-string
Detected template variable interpolation in a JavaScript template string. This is potentially vulnerable to cross-site scripting (XSS) attacks because a malicious actor has control over JavaScript but without the need to use escaped characters. Instead, obtain this variable outside of the template string and ensure your template is properly escaped.

no-direct-write-to-responsewriter
no-direct-write-to-responsewriter
Detected directly writing or similar in ‘http.ResponseWriter.write()’. This bypasses HTML escaping that prevents cross-site scripting vulnerabilities. Instead, use the ‘html/template’ package and render data using ‘template.Execute()’.

When working with web applications that involve rendering user-generated content, it’s important to properly escape any HTML content to prevent Cross-Site Scripting (XSS) attacks. In Go, the text/template package does not automatically escape HTML content, which can leave your application vulnerable to these types of attacks. To mitigate this risk, it’s recommended to use the html/template package instead, which provides built-in functionality for HTML escaping. By using html/template to render your HTML content, you can help to ensure that your web application is more secure and less susceptible to XSS vulnerabilities.

unsafe-template-type
unsafe-template-type
Semgrep could not determine that the argument to ‘template.HTML()’ is a constant. ‘template.HTML()’ and similar does not escape contents. Be absolutely sure there is no user-controlled data in this template. If user data can reach this template, you may have a XSS vulnerability. Instead, do not use this function and use ‘template.Execute()’.
