CVE-2022-41136Network attack vector

Stored XSS via nonce-free preset creation

Published Nov 8, 2022 · Updated Apr 28, 2026

Cross-site request forgery in Shortcodes Ultimate 5.12.0 and earlier allows remote attackers to store malicious JavaScript via forged requests. The ajax_add_preset() handler accepts the settings parameter without nonce validation, then saves insufficiently sanitized preset data that is later rendered without adequate escaping. Exploitation requires a site administrator to visit attacker-controlled content or follow a crafted link, after which the stored script executes when an affected page is opened.
