NewCVE-2026-71315 (opens in a new tab)How to fix?
Upgrade nuxt to version 3.21.10, 4.5.1 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the route rule matching. An attacker can gain unauthorized access to protected pages and sensitive data by crafting requests to mixed-case paths that bypass authentication middleware.
Workaround
This vulnerability can be mitigated by ensuring all route rule keys and page file names are in lowercase, configuring router.options.sensitive to true for case-sensitive routing, or enforcing authentication checks server-side independently of route rules.
