Prior to 3.18.0, Novu's @novu/js In-App Inbox and the @novu/react Inbox component accept a notification call-to-action redirect.url from the v1 cta.data object and pass it through apps/api/src/app/inbox/utils/notification-mapper.ts and packages/js/src/ui/components/Notification/DefaultNotification.tsx to the navigate function in packages/js/src/ui/context/InboxContext.tsx without validating its URL scheme. An authenticated organization member or environment API-key holder can store a javascript: redirect with target _self in an in-app workflow. When a recipient using a Chromium-based browser clicks the notification, window.open executes the redirect in the current inbox-hosting origin, which can expose session material and permit authenticated actions in a customer application or the self-hosted Novu dashboard. This issue is fixed in version 3.18.0.","state":0,"publishedAt":"2026-09-22T16:17:53.95+00:00","modifiedAt":"2026-09-24T21:25:27.05+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/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","score":5.1,"severity":"MEDIUM"}],"references":["https://github.com/novuhq/novu/commit/f105f3d41a4405a75f803634d49f15a967524d8a","https://github.com/novuhq/novu/pull/11453","https://github.com/novuhq/novu/releases/tag/v3.18.0","https://github.com/novuhq/novu/security/advisories/GHSA-8gr3-5j6f-25gp"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75510","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-79"],"productCriteria":[],"sourceDates":{"published":"2026-09-22T16:17:53.950","lastModified":"2026-09-24T21:25:27.050"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
