A vulnerability was detected in quequnlong shiyi-blog up to 1.2.1. Affected is an unknown function of the file blog-admin/src/views/message/message/index.vue of the component Add Message API. The manipulation of the argument body.content results in cross site scripting. The attack can be executed remotely. The project was informed of the problem early through an issue report but has not responded yet.
A stored cross-site scripting vulnerability has been identified in the Shiyi-Blog application, specifically in versions through 1.2.1. The issue arises in the Add Message API, within the file blog-admin/src/views/message/message/index.vue. The vulnerability allows anonymous users to submit malicious scripts via the body.content parameter, which is then stored in the sys_message.content field. When an administrator accesses the message management page, the content is rendered using Vue's v-html directive, executing the embedded scripts. This vulnerability was verified in an authorized testing environment.
It is recommended to sanitize the content before rendering it, using Vue's text interpolation or text nodes instead of v-html. If rich text is necessary, implement a well-maintained whitelist sanitizer to remove harmful elements and attributes.
