Editor-level stored XSS via unescaped image metadata

Published Oct 22, 2024 · Updated Apr 8, 2026

Stored XSS in Category and Taxonomy Meta Fields 1.0.0 and earlier allows remote authenticated users to inject web scripts via image metadata. The wpaft_add_meta_textinput function stores and renders the image meta field value without sufficient sanitization or output escaping. Editor-level access is required, and injected scripts run when a user views the affected page; exposure is limited to multisite installations and installations with unfiltered_html disabled.
