HIGHPre-NVD 8.28.2—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 81% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Nuxt is an open-source web development framework for Vue.js. From 3.21.7 until 3.21.10 and 4.5.1, mixed-case routeRules keys can fail to match case-folded lookups when router.options.sensitive is false and drop appMiddleware authorization gates. This is caused by an incomplete fix for CVE-2026-53721. This issue is fixed in 3.21.10 and 4.5.1.
