      "value": "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."

La explotaci\u00f3n de esta vulnerabilidad es posible cuando es pasada la entrada tanto en modo webpack (archivos MDX en src/pages o archivo MDX importado como componente en c\u00f3digo frontend / React) como en modo datos (consulta de nodos MDX por medio de GraphQL). Mitigaci\u00f3n: Si es debido usar una versi\u00f3n anterior de gatsby-plugin-mdx, la entrada que es pasada al plugin debe ser saneada antes del procesamiento"
