Stored XSS via unsanitized article titles
Published Apr 6, 2026 · Updated Apr 6, 2026
Stored XSS in Feehi CMS 2.1.1 allows remote authenticated users to execute scripts through a crafted article Title value. The article creation and editing module stores the Title field without sanitization or filtering and later renders the stored value to article viewers. An authenticated account with article-creation privileges is required, and execution occurs when another user or administrator views the malicious article, exposing that viewer's session cookie.
