Stored XSS via unescaped image captions

Published Jan 24, 2026 · Updated Jan 24, 2026

Stored XSS in Meta-box GalleryMeta 3.0.1 and earlier allows remote authenticated users to inject scripts through image captions. Image-caption values accepted through the plugin's admin settings are insufficiently sanitized and escaped when the gallery template renders them. Editor-level access or higher is required, and exposure is limited to multisite installations or sites where unfiltered_html is disabled; injected scripts run when a user opens the affected gallery page.
