From 1.143.12 until 1.169.39 for @tanstack/start-server-core, 1.168.60 for @tanstack/react-start, 1.168.57 for @tanstack/solid-start, and 1.168.56 for @tanstack/vue-start, an unauthenticated attacker can place non-public fields in a server-function request payload so that attacker-controlled middleware state reaches the error path and a response-shaped object is accepted as an HTTP response. A crafted server-function URL can therefore return attacker-controlled HTML from the application's origin; when a visitor opens the URL, the injected script can access same-origin data and issue requests with the visitor's authority. This issue is fixed in @tanstack/start-server-core 1.169.39, @tanstack/react-start 1.168.60, @tanstack/solid-start 1.168.57, and @tanstack/vue-start 1.168.56."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"TanStack","product":"router","versions":[{"version":"< release-2026-09-30-1747","status":"affected"}]},{"vendor":"@tanstack","product":"react-start","versions":[{"version":">= 1.143.12, < 1.168.60","status":"affected"}]},{"vendor":"@tanstack","product":"solid-start","versions":[{"version":">= 1.143.12, < 1.168.57","status":"affected"}]},{"vendor":"@tanstack","product":"start-server-core","versions":[{"version":">= 1.143.12, < 1.169.39","status":"affected"}]},{"vendor":"@tanstack","product":"vue-start","versions":[{"version":">= 1.143.12, < 1.168.56","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N","baseScore":9.3,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":5.8}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-14T15:19:40.392223Z","id":"CVE-2026-102989","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-79"}]}],"references":[{"url":"https://github.com/TanStack/router/commit/d521abd71c69f1ff010bb3def4d417cb5fa058cb","source":"security-advisories@github.com"},{"url":"https://github.com/TanStack/router/pull/8573","source":"security-advisories@github.com"},{"url":"https://github.com/TanStack/router/releases/tag/release-2026-09-30-1747","source":"security-advisories@github.com"},{"url":"https://github.com/TanStack/router/security/advisories/GHSA-qx66-fv34-fjm8","source":"security-advisories@github.com"}]}}]}
