Title
Craft CMS 5.0.0 before 5.10.14 DOM XSS via returnUrl in 2FA Verification
Summary
Craft CMS 5.0.0 before 5.10.14 contains a DOM-based cross-site scripting vulnerability in the control panel login and 2FA verification flow, where a user-controlled returnUrl accepting javascript: URLs is used in client-side navigation. Attackers can lure a 2FA-enabled victim into opening a crafted /admin/login?verify=1 URL between password submission and TOTP verification, executing JavaScript in the authenticated control panel with the victim's permissions.
