This is currently the only way to be able to transform markdown into ADF, which we heavily depend on for API integrations. There is a security vulnerability reported for one of the dependencies:
Risk Level High: node-fetch is vulnerable to Exposure of Sensitive information to an Unauthorized Actor
Package: node-fetch
Patched in: >=2.6.7
Dependency of: @atlaskit/editor-markdown-transformer
Path: @atlaskit/editor-markdown-transformer > @atlaskit/editor-common > @atlaskit/media-card > @atlaskit/editor-shared-styles > styled-components > fbjs > isomorphic-fetch > node-fetch
More info: node-fetch is vulnerable to Exposure of Sensitive Information to an Unauthorized Actor · CVE-2022-0235 · GitHub Advisory Database · GitHub
Is this something that the team is aware of or planning to update? Would love to help contribute, but I know that may not be possible since it is now closed source.
