Description
Nuxt from 4.6.0 before 4.6.2 contains a route parameter confusion vulnerability in getRouterParam and getRouterParams that lets attackers return a parameter value different from the one h3 matched by sending paths containing an encoded question mark (%3F). Attackers can craft requests where authorization checks use the Nuxt helper value while resource selection uses event.context.params, allowing access to unauthorized resources.
