Repostat Vulnerable to Reflected Cross-Site Scripting (XSS) via repo prop in RepoCard

概要

Repostat Vulnerable to Reflected Cross-Site Scripting (XSS) via repo prop in RepoCard

原文の説明

取得元が公開している説明をそのまま載せています (多くは英語)。

Repostat is a React component to fetch and display GitHub repository info. Prior to version 1.0.1, the RepoCard component is vulnerable to Reflected Cross-Site Scripting (XSS). The vulnerability occurs because the component uses React's dangerouslySetInnerHTML to render the repository name (repo prop) during the loading state without any sanitization. If a developer using this package passes unvalidated user input directly into the repo prop (for example, reading it from a URL query parameter), an attacker can execute arbitrary JavaScript in the context of the user's browser. In version 1.0.1, the use of dangerouslySetInnerHTML has been removed, and the repo prop is now safely rendered using standard React JSX data binding, which automatically escapes HTML entities.
