CVE-2022-25863

npm/gatsby

Deserialization of Untrusted Data

The package gatsby-plugin-mdx before 2.14.1, from 3.0.0 and before 3.15.2 is 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.

All versions before 2.14.1, all versions starting from 3.0.0 before 3.15.2

Upgrade to version 2.14.1, 3.15.2, or above.
