From versions 3.4.3 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, navigateTo() with external: true generates a server-side HTML redirect body containing a <meta http-equiv=\"refresh\"> tag. The destination URL is only sanitized by replacing \" with %22, leaving <, >, &, and ' unencoded. An attacker who can influence the URL passed to navigateTo(url, { external: true }) can break out of the content=\"…\" attribute and inject arbitrary HTML/JavaScript that executes under the application's origin. This issue has been patched in versions 3.21.6 and 4.4.6."}],"source":{"advisory":"GHSA-fx6j-w5w5-h468","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-fx6j-w5w5-h468","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-12T14:03:21.230017Z","id":"CVE-2026-45669","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-12T14:07:21.725Z"}}]}}
