Attackers can craft requests where authorization checks use the Nuxt helper value while resource selection uses event.context.params, allowing access to unauthorized resources.","cvssScore":3.7,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-436"],"vendors":[],"products":[],"references":[{"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-w7gw-66vg-99gq","tags":[]},{"url":"https://www.vulncheck.com/advisories/nuxt-4.6.0-before-4.6.2-route-param-confusion-via-getrouterparam","tags":[]}],"exploitRefs":[{"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-w7gw-66vg-99gq","tags":[]}],"hasPoc":true,"ai":null}
