{"id":"CVE-2026-114139","state":"PUBLISHED","title":"Sentry-Javascript: Middleware Bypass when using Tunnel route","description":"Sentry-Javascript is an official Sentry SDKs for JavaScript. 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.","publishedAt":"2026-10-21T20:14:34.419Z","updatedAt":"2026-10-28T01:38:14.177Z","severity":{"score":9.1,"label":"Critical","version":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["getsentry sentry-javascript"],"affected":[{"vendor":"getsentry","product":"sentry-javascript","versions":[{"version":">= 9.36.0, < 9.47.2","status":"affected"},{"version":">= 10.0.0-alpha.0, < 10.75.2","status":"affected"},{"version":">= 11.0.0-alpha.0, < 11.0.0-rc.1","status":"affected"}]}],"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"],"weaknesses":["CWE-693"],"ingestedAt":"2026-10-29T20:10:43.281Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/114xxx/CVE-2026-114139.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-114139","state":"PUBLISHED","datePublished":"2026-10-21T20:14:34.419Z","dateUpdated":"2026-10-28T01:38:14.177Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-20T21:53:58.473Z"},"containers":{"cna":{"title":"Sentry-Javascript: Middleware Bypass when using Tunnel route","descriptions":[{"lang":"en","value":"Sentry-Javascript is an official Sentry SDKs for JavaScript.
