What is CVE-2026-120309?

The Nuxt framework versions before 4.6.2 are susceptible to a route parameter confusion vulnerability. This issue arises from the getRouterParam and getRouterParams functions, where attackers can exploit crafted requests containing an encoded question mark (%3F). This manipulation could permit unauthorized access to resources, as the system may use incorrect parameter values for authorization checks, allowing the selection of unauthorized content. Developers are advised to update to the latest version to mitigate this risk.

Affected Version(s)

nuxt 4.6.0 < 4.6.2

nuxt 4.6.0 < 4.6.2

nuxt 4.6.2
