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":"2026-10-21T20:14:34.419+00:00","modifiedAt":"2026-10-21T20:14:34.419+00:00","affected":[{"ecosystem":"Vendor product","name":"sentry-javascript","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getsentry\",\n                    \"product\": \"sentry-javascript\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 9.36.0, < 9.47.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 10.0.0-alpha.0, < 10.75.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 11.0.0-alpha.0, < 11.0.0-rc.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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,"severity":"CRITICAL"}],"references":["https://github.com/getsentry/sentry-javascript/security/advisories/GHSA-mchm-gjx6-7h55","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/commit/878b685c85dc12045e47e1932c96f5381d7ac532","https://github.com/getsentry/sentry-javascript/commit/c122aac4f29541eb6da494296822c91eab3cf5ae","https://github.com/getsentry/sentry-javascript/commit/d525a2f6015b47384bc139c30d58e0d5435d52e5","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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-114139","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114139","identifiers":["CVE-2026-114139"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
