{"id":"CVE-2025-59414","aliases":["GHSA-p6jq-8vc4-79f6"],"url":"https://o3.security/vulnerability/CVE-2025-59414","summary":"Nuxt Client-Side Path Traversal in Nuxt Island Payload Revival","details":"Nuxt is an open-source web development framework for Vue.js. Prior to 3.19.0 and 4.1.0, A client-side path traversal vulnerability in Nuxt's Island payload revival mechanism allowed attackers to manipulate client-side requests to different endpoints within the same application domain when specific prerendering conditions are met. The vulnerability occurs in the client-side payload revival process (revive-payload.client.ts) where Nuxt Islands are automatically fetched when encountering serialized __nuxt_island objects. During prerendering, if an API endpoint returns user-controlled data containing a crafted __nuxt_island object, he data gets serialized with devalue.stringify and stored in the prerendered page. When a client navigates to the prerendered page, devalue.parse deserializes the payload. The Island reviver attempts to fetch /__nuxt_island/${key}.json where key could contain path traversal sequences. Update to Nuxt 3.19.0+ or 4.1.0+.","published":"2025-09-17T18:39:38.193Z","modified":"2026-08-12T03:51:10.577872759Z","cvss":{"score":3.1,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N"},"epss":{"score":0.00372,"percentile":0.29914,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"nuxt","fixedVersion":"3.19.0"},{"ecosystem":"npm","name":"nuxt","fixedVersion":"4.1.0"}],"fix":{"url":"https://github.com/nuxt/nuxt/commit/2566d2046bccb158d98fb13e42ce4b2c33fb2595","label":"nuxt/nuxt@2566d20"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59414.json"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-p6jq-8vc4-79f6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59414"},{"type":"FIX","url":"https://github.com/nuxt/nuxt/commit/2566d2046bccb158d98fb13e42ce4b2c33fb2595"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.577872759Z"}}
