Stored script execution via album description

Published Dec 17, 2025 · Updated Dec 17, 2025

Stored XSS in album descriptions in Zenphoto 1.6 allows remote authenticated users to execute scripts when visitors view an album. The album editor stores permitted iframe or script markup from the description field, and album rendering emits that markup without neutralizing executable HTML. Backend album-editing access is required, and execution occurs in the browser context of a user who views the crafted album.
