From 15.0.0 until 15.5.27 and 16.3.8, self-hosted applications using the Pages Router with statically generated or Incremental Static Regeneration pages can key a response cache entry without sufficiently binding it to the source route. A request can replace one page's cache entry with content from a different route, causing the affected page to serve incorrect content to every visitor until revalidation. Applications deployed on Vercel are not affected. 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-2026-94543.json)\n\n## Package advisory (CVE-2026-94543)\n\nAffected packages:\n\n- `next >= 15.0.0, < 15.5.27`\n- `next >= 16.0.0, < 16.3.8`\n\nPatched in:\n\n- `next 15.5.27`\n- `next 16.3.8`\n\nSource: https://github.com/advisories/GHSA-4jqv-mc3x-m676","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":215864,"id":"CVE-2026-94543","ts":1791213929781,"field":"cvss","old":"6.3","new":"5.3"}]}
