DescriptionCVE.org

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.
