{"id":"CVE-2025-27415","aliases":["GHSA-jvhm-gjrh-3h93"],"url":"https://o3.security/vulnerability/CVE-2025-27415","summary":"Nuxt allows DOS via cache poisoning with payload rendering response","details":"### Summary\n\nBy sending a crafted HTTP request to a server behind an CDN, it is possible in some circumstances to poison the CDN cache and highly impacts the availability of a site.\n\nIt is possible to craft a request, such as `https://mysite.com/?/_payload.json` which will be rendered as JSON. If the CDN in front of a Nuxt site ignores the query string when determining whether to cache a route, then this JSON response could be served to future visitors to the site.\n\n### Impact\n\nAn attacker can perform this attack to a vulnerable site in order to make a site unavailable indefinitely. It is also possible in the case where the cache will be reset to make a small script to send a request each X seconds (=caching duration) so that the cache is permanently poisoned making the site completely unavailable.\n\n\n## Conclusion : \n\nThis is similar to a vulnerability in Next.js that resulted in CVE-2024-46982 (and see [this article](https://zhero-web-sec.github.io/research-and-things/nextjs-cache-and-chains-the-stale-elixir), in particular the \"Internal URL parameter and pageProps\" part, the latter being very similar to the one concerning us here.)","published":"2025-03-19T19:02:04.824Z","modified":"2026-08-12T03:51:15.014494510Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00376,"percentile":0.31316,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"nuxt","fixedVersion":"3.16.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/27xxx/CVE-2025-27415.json"},{"type":"ADVISORY","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-jvhm-gjrh-3h93"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-27415"},{"type":"PACKAGE","url":"https://github.com/nuxt/nuxt"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:15.014494510Z"}}
