CVE-2026-114139
CriticalCVSS 9.1Exploitation Probability (EPSS)
Low risk34th percentile - higher than 34% of all known CVEs
Summary
In the webpack integration for @sentry/nextjs from 9.36.0 until 9.47.2, 10.75.2, and 11.0.0-rc.1, application middleware is skipped for every request path under a configured tunnelRoute. When an application route collides with the tunnel path, an unauthenticated request can reach that route without middleware authorization.
Risk Assessment
An unauthenticated attacker may reach protected routes when middleware is the only authorization control, risking authentication bypass.
Recommendation
Upgrade @sentry/nextjs to 9.47.2, 10.75.2, or 11.0.0-rc.1 and ensure authorization does not rely solely on middleware.

Original NVD description (English source)
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.
