{"id":"CVE-2026-56326","summary":"Nuxt - Server-Side Open Redirect via Path-Normalization Bypass in navigateTo","details":"Nuxt versions 4.0.0 before 4.4.7 and 3.x before 3.21.7 contain a server-side open redirect vulnerability in navigateTo that fails to properly validate path-normalized payloads like /..//evil.com and /.//evil.com. Attackers can bypass external-host checks using path-normalization techniques to redirect users to attacker-controlled sites via the Location header or meta-refresh, enabling phishing and OAuth authorization-code theft.","aliases":["CVE-2026-56697","CVE-2026-56698","GHSA-c9cv-mq2m-ppp3"],"modified":"2026-07-08T08:26:07.961325723Z","published":"2026-06-22T21:04:50.975Z","database_specific":{"cwe_ids":["CWE-601"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56326.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56326.json"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-c9cv-mq2m-ppp3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56326"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/nuxt-server-side-open-redirect-via-path-normalization-bypass-in-navigateto"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/1f2dd5e78c77576437138e97671965573c232835"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/2cce6fb02e621196d56df92e05594e07469b5a6d"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"d991a55ec36f5ac61de0af7d0b018a150153445b"},{"fixed":"fd806be61503f6ccad099c070a5d803777ba8a57"},{"introduced":"8aacdde48e8388c8bb11b9a5c2f59935341bfcfd"},{"fixed":"b7d57903b947e788fadfcfdf88be7951943731bf"},{"fixed":"1f2dd5e78c77576437138e97671965573c232835"},{"fixed":"2cce6fb02e621196d56df92e05594e07469b5a6d"}],"database_specific":{"extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.21.7"},{"introduced":"4.0.0"},{"fixed":"4.4.7"}],"cpe":"cpe:2.3:a:nuxt:nuxt:*:*:*:*:*:*:*:*","source":["CPE_RANGE","REFERENCES"]}}],"versions":["v4.4.6","v3.21.6","v3.21.5","v4.4.5","v3.21.4","v4.4.4","v3.21.3","v4.4.3","v4.4.2","v3.21.2","v4.4.1","v4.4.0","v4.3.1","v3.21.1","v3.21.0","v4.3.0","v3.20.2","v4.2.2","v3.20.1","v4.2.1","v3.20.0","v4.2.0","v3.19.3","v4.1.3","v3.19.2","v4.1.2","v3.19.1","v4.1.1","v3.19.0","v4.1.0","v3.18.1","v4.0.3","v3.18.0","v4.0.2","v4.0.1","v4.0.0","v3.17.7","v3.17.6","v3.17.5","v3.17.4","v3.17.3","v3.17.2","v3.17.1","v3.17.0","v3.16.2","v3.16.1","v3.16.0","v3.15.4","v3.15.3","v3.15.2","v3.15.1","v3.15.0","v3.14.1592","v3.14.159","v3.14.0","v3.13.2","v3.13.1","v3.13.0","v3.12.4","v3.12.3","v3.12.2","v3.12.1","v3.12.0","v3.11.2","v3.11.1","v3.11.0","v3.10.3","v3.10.2","v3.10.1","v3.10.0","v3.9.3","v3.9.2","v3.9.1","v3.9.0","v3.8.2","v3.8.1","v3.8.0","v3.7.4","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.5","v3.6.4","v3.6.3","v3.6.2","v3.6.1","v3.6.0","v3.5.3","v3.5.2","v3.5.1","v3.5.0","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.2","v3.1.1","3.1.1","v3.1.0","v3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-56326.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
