Stored XSS via unencoded item category
Published Feb 13, 2026 · Updated Feb 13, 2026
Stored XSS in OpenSourcePOS 3.4.1 allows remote authenticated users to execute scripts in barcode-preview viewers' browsers. The Items module stores the user-supplied Category field, and the Generate Barcode view renders that value without HTML encoding. An account with item-management permission must plant the value, and another user must generate labels for that item, exposing the viewer's session and page actions.
