CVE-2020-20584Network attack vector

Browser script execution via profile form input

Published Jul 8, 2021 · Updated Jul 9, 2026

Cross-site scripting in baigo CMS 4.0-beta-1 allows remote attackers to execute arbitrary script in a user's browser through a profile form. The /public/console/profile/info-submit/ handler places the post form parameter into browser-rendered output without neutralizing script or HTML. Exploitation requires user interaction, and the injected code runs in the affected user's web context with access to page data and actions.
