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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"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"}]}]}],"metrics":{"cvssMetricV40":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":9.1,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"PRESENT","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"HIGH","vulnIntegrityImpact":"HIGH","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-693"}]}],"references":[{"url":"https://github.com/getsentry/sentry-javascript/commit/878b685c85dc12045e47e1932c96f5381d7ac532","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/commit/c122aac4f29541eb6da494296822c91eab3cf5ae","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/commit/d525a2f6015b47384bc139c30d58e0d5435d52e5","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/pull/24499","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/pull/24565","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/pull/24760","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/releases/tag/10.75.2","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/releases/tag/11.0.0-rc.1","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/releases/tag/9.47.2","source":"security-advisories@github.com"},{"url":"https://github.com/getsentry/sentry-javascript/security/advisories/GHSA-mchm-gjx6-7h55","source":"security-advisories@github.com"}]}
