From 9.36.0 until 9.47.2, 10.75.2, and 11.0.0-rc.1, the webpack integration for @sentry/nextjs skips application middleware for every request path under a configured tunnelRoute, while the tunnel rewrite serves only the exact tunnel path with valid o and p query parameters. When an application route directly collides with the tunnel path or a root dynamic segment resolves under it, an unauthenticated request can reach that route without middleware authorization. Exploitation requires tunnelRoute, a webpack build, a colliding route, and middleware being the only authorization control. This issue is fixed in versions 9.47.2, 10.75.2, and 11.0.0-rc.1.","state":0,"publishedAt":"2026-10-21T21:17:56.353+00:00","modifiedAt":"2026-10-28T02:17:05.363+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/getsentry/sentry-javascript/commit/878b685c85dc12045e47e1932c96f5381d7ac532","https://github.com/getsentry/sentry-javascript/commit/c122aac4f29541eb6da494296822c91eab3cf5ae","https://github.com/getsentry/sentry-javascript/commit/d525a2f6015b47384bc139c30d58e0d5435d52e5","https://github.com/getsentry/sentry-javascript/pull/24499","https://github.com/getsentry/sentry-javascript/pull/24565","https://github.com/getsentry/sentry-javascript/pull/24760","https://github.com/getsentry/sentry-javascript/releases/tag/10.75.2","https://github.com/getsentry/sentry-javascript/releases/tag/11.0.0-rc.1","https://github.com/getsentry/sentry-javascript/releases/tag/9.47.2","https://github.com/getsentry/sentry-javascript/security/advisories/GHSA-mchm-gjx6-7h55"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-114139","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-693"],"productCriteria":[],"sourceDates":{"published":"2026-10-21T21:17:56.353","lastModified":"2026-10-28T02:17:05.363"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
