^1.10.1->^2.0.0GitHub Vulnerability Alerts
CVE-2022-25863
Impact
The gatsby-plugin-mdx plugin prior to versions 3.15.2 and 2.14.1 passes input through to the
gray-matternpm package, which is vulnerable to JavaScript injection in its default configuration, unless input is sanitized. The vulnerability is present when passing input in both webpack (MDX files insrc/pagesor MDX file imported as component in frontend / React code) and data mode (querying MDX nodes via GraphQL). Injected JavaScript executes in the context of the build server.To exploit this vulnerability untrusted/unsanitized input would need to be sourced or added into an MDX file. The following MDX payload demonstrates a vulnerable configuration:
Patches
A patch has been introduced in
gatsby-plugin-mdx@3.15.2andgatsby-plugin-mdx@2.14.1which mitigates the issue by disabling thegray-matterJavaScript Frontmatter engine. The patch introduces a new option,JSFrontmatterEnginewhich is set tofalseby default. When settingJSFrontmatterEnginetotrue, input passed togatsby-plugin-mdxmust be sanitized before processing to avoid a security risk. Warnings are displayed when enablingJSFrontmatterEnginetotrueor if it appears that the MDX input is attempting to use the Frontmatter engine.Workarounds
If an older version of
gatsby-plugin-mdxmust be used, input passed into the plugin should be sanitized ahead of processing.We encourage projects to upgrade to the latest major release branch for all Gatsby plugins to ensure the latest security updates and bug fixes are received in a timely manner.
