property

The property rule in eslint-plugin-no-unsanitized perform basic security checks for property assignments. The idea of these checks is to ensure that certain insecure coding patterns are avoided in your codebase. We encourage developers to use HTML sanitizers or escapers to mitigate those insecure patterns.

Unsafe assignment to innerHTML or outerHTML

This error message suggests that you are using an unsafe coding pattern. Please do not simply assign variables to innertHTML, as this might cause Cross-Site Scripting (XSS) vulnerabilities. We encourage you to construct DOM nodes using createElement and changing their attributes (e.g., textContent, classList) instead.
