WordPress Core is vulnerable to information disclosure via the REST-API in versions up to 6.0.3. The REST API endpoint for terms and tags did not perform enough validation on the user requesting information about terms and tags for a given post.
This made it possible for users with access to terms and tags, such as a contributor, to determine those details on all posts not belonging to them, even when in a private status. This does not reveal critical information.
Not sure which version you run? Run a passive check — it reads public files only.
