SCA: security update for gatsby-plugin-mdx (GHSA-mj46-r4gr-5x83)

critical Tenable Cloud Security Plugin ID 416990

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2022-25863)
