Medium (5.3) in nuxt nuxt. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in nuxt 3.21.7, 4.4.7.
Nuxt versions 4.0.0 before 4.4.7 and 3.x before 3.21.7 fail to validate script-capable URLs in the navigateTo open option, allowing client-side script execution. Attackers can supply javascript: URLs through the open parameter to execute arbitrary scripts in the application's origin when user-controlled input is passed to navigateTo.
