Official description

Tina is a headless content management system. Prior to version 2.2.2, a path traversal vulnerability in @tinacms/graphql allows unauthenticated users to write and overwrite arbitrary files within the project root.

The impact includes the ability to replace critical server configuration files and potentially execute arbitrary commands by sabotaging build script. This issue has been patched in version 2.2.2.
