CVE-2023-22491

Disclosure Date: January 13, 2023
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

Gatsby is a free and open source framework based on React that helps developers build websites and apps. The gatsby-transformer-remark plugin prior to versions 5.25.1 and 6.3.2 passes input through to the gray-matter npm package, which is vulnerable to JavaScript injection in its default configuration, unless input is sanitized. The vulnerability is present in gatsby-transformer-remark when passing input in data mode (querying MarkdownRemark 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 by or added into a file processed by gatsby-transformer-remark. A patch has been introduced in gatsby-transformer-remark@5.25.1 and gatsby-transformer-remark@6.3.2 which mitigates the issue by disabling the gray-matter JavaScript Frontmatter engine. As a workaround, if an older version of gatsby-transformer-remark must be used, input passed into the plugin should be sanitized ahead of processing. It is encouraged for 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.
