{"id":"CVE-2025-27415","state":"PUBLISHED","title":"Nuxt allows DOS via cache poisoning with payload rendering response","description":"Nuxt is an open-source web development framework for Vue.js. Prior to 3.16.0, by 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. It 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. An 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. This vulnerability is fixed in 3.16.0.","publishedAt":"2025-03-19T19:02:04.824Z","updatedAt":"2025-03-19T19:22:25.732Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["nuxt nuxt"],"affected":[{"vendor":"nuxt","product":"nuxt","versions":[{"version":">= 3.0.0, < 3.16.0","status":"affected"}]}],"references":["https://github.com/nuxt/nuxt/security/advisories/GHSA-jvhm-gjrh-3h93"],"weaknesses":["CWE-349"],"ingestedAt":"2026-10-29T20:08:47.682Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/27xxx/CVE-2025-27415.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-27415","state":"PUBLISHED","datePublished":"2025-03-19T19:02:04.824Z","dateUpdated":"2025-03-19T19:22:25.732Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-02-24T15:51:17.268Z"},"containers":{"cna":{"title":"Nuxt allows DOS via cache poisoning with payload rendering response","descriptions":[{"lang":"en","value":"Nuxt is an open-source web development framework for Vue.js.
