CVE-2026-5253 Details
Description
A weakness has been identified in bufanyun HotGo 1.0/2.0. Affected by this vulnerability is an unknown functionality of the file /web/src/layout/components/Header/MessageList.vue of the component editNotice Endpoint. Executing a manipulation can lead to cross site scripting. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A stored cross-site scripting (XSS) vulnerability exists in bufanyun HotGo versions 1.0 and 2.0. The issue arises in the editNotice endpoint, where user-supplied content is accepted without proper sanitization or validation. This content is stored in the database and later rendered on the frontend using Vue.js v-html directive, which also lacks sanitization. As a result, authenticated attackers can inject arbitrary JavaScript that executes in the browsers of users viewing the notice, potentially leading to session hijacking or credential theft.
It is recommended to implement HTML sanitization using libraries like DOMPurify, avoid using v-html in favor of safer Vue.js rendering options, and validate input against a whitelist of allowed HTML tags and attributes.
