Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the Search component (blog-web/src/components/Search/index.vue). The highlightKeyword function inserts HTML mark tags into article titles and summaries without HTML entity encoding, then renders the result via Vue's v-html directive. Attackers with sys:article:add or sys:article:update permissions can inject arbitrary HTML/JavaScript through the title or summary fields when creating or modifying articles. The malicious payload is stored in the database (sys_article table) and executed when any unauthenticated visitor searches and views the published article. This enables session hijacking, credential theft, or malicious actions within the context of the affected page.
