CVE-2026-90564 Details
Description
A vulnerability was identified in quequnlong shiyi-blog 1.0.0-1.2.1. This impacts the function SysChatMsgMapper.getChatMsgList of the file blog-web/src/views/chat/index.vue of the component chat sendMsg Endpoint. Such manipulation of the argument chat_msg leads to cross site scripting. The attack may be performed from remote. The project was informed of the problem early through an issue report but has not responded yet.
A cross-site scripting (XSS) vulnerability has been identified in Quequnlong Shiyi-Blog versions 1.0.0 through 1.2.1. The issue arises in the chat component, specifically within the 'sendMsg' endpoint. When a user sends a message, the content is stored in a way that allows for the injection of scripts. These messages are then broadcasted to all users via WebSocket. Other logged-in users can see the injected scripts executed in their browsers when they view the chat history or receive real-time message updates.
It is recommended to sanitize chat messages before rendering them in the application. Avoid using 'v-html' to display user-generated content without proper sanitization.
