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.","cvss_v4":{"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","score":9.1},"cvss_v3":null,"cwes":["CWE-693"],"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"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-114139","score":0.0051,"percentile":0.43214,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-mchm-gjx6-7h55","url":"https://osv.dev/vulnerability/GHSA-mchm-gjx6-7h55","summary":"Sentry-Javascript: Middleware Bypass when using Tunnel route","modified":"2026-10-22T16:00:09.116997075Z","packages":[{"ecosystem":"npm","name":"@sentry/nextjs","purl":"pkg:npm/%40sentry/nextjs","ranges":[">=9.36.0 <9.47.2"],"fixed":["9.47.2"]},{"ecosystem":"npm","name":"@sentry/nextjs","purl":"pkg:npm/%40sentry/nextjs","ranges":[">=10.0.0-alpha.0 <10.75.2"],"fixed":["10.75.2"]},{"ecosystem":"npm","name":"@sentry/nextjs","purl":"pkg:npm/%40sentry/nextjs","ranges":[">=11.0.0-alpha.0 <11.0.0-rc.1"],"fixed":["11.0.0-rc.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
