CVE-2022-25863

CRITICAL 9.8EPSS 1.96%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.96%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
