CVE-2022-40699Network attack vector

Subscriber-level stored XSS via unsanitized shortcodes

Published Mar 16, 2023 · Updated Apr 28, 2026

Stored cross-site scripting in Dario Curvino YASR 3.1.2 and earlier allows remote authenticated users to execute scripts through shortcodes. The plugin fails to sanitize shortcode input and escape it before rendering, storing attacker-supplied web scripts in pages. Subscriber-level access is sufficient, and the scripts run in a visitor's browser when the injected page is opened, enabling actions in that visitor's session.
