SCA: security update for repostat (GHSA-fm8c-6m29-rp6j)

medium Tenable Self-Hosted Container Security Plugin ID 438009

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-27612)
