{"id":"GHSA-jvhm-gjrh-3h93","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.)","aliases":["CVE-2025-27415"],"modified":"2025-03-20T19:31:04Z","published":"2025-03-19T19:54:25Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2025-03-19T19:54:25Z","nvd_published_at":"2025-03-19T19:15:47Z","cwe_ids":["CWE-349"]},"references":[{"type":"WEB","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"}],"affected":[{"package":{"name":"nuxt","ecosystem":"npm","purl":"pkg:npm/nuxt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.16.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-jvhm-gjrh-3h93/GHSA-jvhm-gjrh-3h93.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
