Cross-Site Scripting in Gitea Search Input Before

Executive Summary

This vulnerability in Gitea before version 1.22.2 is a cross-site scripting (XSS) issue caused by the use of the Vue.js directive `v-html` in the search input box for creating tags and branches. Using `v-html` allows raw HTML to be rendered, which can enable attackers to inject malicious scripts. The vulnerability was fixed by replacing `v-html` with `v-text`, which safely renders text without interpreting it as HTML, thereby preventing potential script injection and related security risks.
