{"id":"GHSA-v2v2-hph8-q5xp","summary":"@fastify/reply-from JSON Content-Type parsing confusion","details":"### Impact\n\nThe main repo of fastify use [fast-content-type-parse](https://github.com/fastify/fast-content-type-parse) to parse request Content-Type, which will [trim after split](https://github.com/fastify/fast-content-type-parse/blob/2776d054dd48e9ce40b8d5e5ff9b46fee82b95f1/index.js#L59).\n\nThe [fastify-reply-from](https://github.com/fastify/fastify-reply-from/blob/b79a22d6eb9a0b52cfbe8eb2cb22ad65f5a39e64/index.js#L118C14-L118C14) have not use this repo to unify the parse of Content-Type, which [won't trim](https://github.com/fastify/fastify-reply-from/blob/b79a22d6eb9a0b52cfbe8eb2cb22ad65f5a39e64/index.js#L118C14-L118C14).\n\nAs a result, a reverse proxy server built with `@fastify/reply-from` could misinterpret the incoming body by passing an header `ContentType: application/json ; charset=utf-8`. This can lead to bypass of security checks.\n\n### Patches\n\n`@fastify/reply-from` v9.6.0 include the fix. \n\n### Workarounds\n\nThere are no known workarounds.\n\n### References\n\nHackerone Report: https://hackerone.com/reports/2295770.","aliases":["CVE-2023-51701"],"modified":"2024-01-08T15:55:16Z","published":"2024-01-08T15:22:40Z","database_specific":{"github_reviewed_at":"2024-01-08T15:22:40Z","nvd_published_at":"2024-01-08T14:15:46Z","cwe_ids":["CWE-444"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/fastify/fastify-reply-from/security/advisories/GHSA-v2v2-hph8-q5xp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-51701"},{"type":"WEB","url":"https://github.com/fastify/fastify-reply-from/commit/cbd7c17c09e6476268e34f5e499a6b923e8acc18"},{"type":"PACKAGE","url":"https://github.com/fastify/fastify-reply-from"},{"type":"WEB","url":"https://github.com/fastify/fastify-reply-from/releases/tag/v9.6.0"}],"affected":[{"package":{"name":"@fastify/reply-from","ecosystem":"npm","purl":"pkg:npm/%40fastify/reply-from"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.6.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-v2v2-hph8-q5xp/GHSA-v2v2-hph8-q5xp.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:L/I:N/A:N"}]}
