Stored XSS via unescaped plugin settings
Published Nov 8, 2021 · Updated Aug 3, 2024
Stored XSS in Dan Kirshner Qwizcards before 3.62 allows remote authenticated users to execute script through plugin settings. Settings processing stores administrator-supplied HTML without sufficient sanitization, and later output renders the stored value without context-appropriate escaping. High-privilege access to the WordPress administration interface and a later page view are required; script executes in the viewer’s browser context.
