{"id":"CVE-2022-25863","aliases":["GHSA-mj46-r4gr-5x83","SNYK-JS-GATSBYPLUGINMDX-2405699"],"url":"https://o3.security/vulnerability/CVE-2022-25863","summary":"Deserialization of Untrusted Data","details":"The package gatsby-plugin-mdx before 2.14.1, from 3.0.0 and before 3.15.2 are vulnerable to Deserialization of Untrusted Data when passing input through to the gray-matter package, due to its default configurations that are missing input sanitization. Exploiting this vulnerability is possible when passing input in both webpack (MDX files in src/pages or MDX file imported as a component in frontend / React code) and data mode (querying MDX nodes via GraphQL). Workaround: If an older version of gatsby-plugin-mdx must be used, input passed into the plugin should be sanitized ahead of processing.","published":"2022-06-10T20:00:19.275Z","modified":"2026-07-15T01:49:12.305948134Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:P"},"epss":null,"cisaKev":null,"exploitsKnown":3,"affectedPackages":[{"ecosystem":"npm","name":"gatsby-plugin-mdx","fixedVersion":"2.14.1"},{"ecosystem":"npm","name":"gatsby-plugin-mdx","fixedVersion":"3.15.2"}],"fix":{"url":"https://github.com/gatsbyjs/gatsby/pull/35830","label":"gatsbyjs/gatsby#35830"},"references":[{"type":"WEB","url":"https://drive.google.com/file/d/1EoCzbwTWOM8-fjvwMbH3bqcZ2iKksxTW/view?usp=sharing"},{"type":"WEB","url":"https://github.com/gatsbyjs/gatsby/pull/35830/commits/f214eb0694c61e348b2751cecd1aace2046bc46e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/25xxx/CVE-2022-25863.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-25863"},{"type":"ADVISORY","url":"https://snyk.io/vuln/SNYK-JS-GATSBYPLUGINMDX-2405699"},{"type":"FIX","url":"https://github.com/gatsbyjs/gatsby/pull/35830"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:12.305948134Z"}}
