From 15.0.0 until 15.5.27 and 16.3.8, applications with a root-level catch-all page and statically generated or Incremental Static Regeneration routes can use a shared response cache key that is insufficiently scoped to the source route. A single unauthenticated crafted request can poison that cache, causing cross-user content substitution or persistent denial of service until the poisoned entry is revalidated or replaced. This issue is fixed in versions 15.5.27 and 16.3.8.\n\n## Affected\n\n- `next.js >= 15.0.0, < 15.5.27`\n- `next.js >= 16.0.0, < 16.3.8`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `next.js 16.3.8`\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat Trusted Artifact Signer · no fix planned: Red Hat Trusted Artifact Signer, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · updated 2026-10-05 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-94484.json)\n\n## Package advisory (CVE-2026-94484)\n\nAffected packages:\n\n- `next >= 16.0.0, < 16.3.8`\n- `next >= 15.0.0, < 15.5.27`\n\nPatched in:\n\n- `next 16.3.8`\n- `next 15.5.27`\n\nSource: https://github.com/advisories/GHSA-mcj8-r9mp-w47p","depth":"sunlit","depthScore":26,"depthScoreParts":{"impact":26.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":215860,"id":"CVE-2026-94484","ts":1791213928843,"field":"cvss","old":"6.3","new":"4.8"}]}
