CVE-2022-4753Public exploitNetwork attack vector

Contributor-level stored XSS via unescaped shortcode attribute

Published Jan 23, 2023 · Updated Apr 3, 2025

Stored XSS in Twinpictures Print-O-Matic before 2.1.8 allows remote authenticated users to execute scripts through a crafted shortcode. The affected shortcode places its class attribute into page output without validation or escaping, so injected event-handler markup remains stored in a post. Contributor access is sufficient, and the script runs when a higher-privileged administrator views the affected page, allowing actions in the administrator’s browser context.
