Miggo AIRoot Cause Analysis

The vulnerability stems from processing the 'fileUrl' header in HTTP requests. TikaResource.parse() is the primary request handler for tika-server endpoints. In vulnerable versions, this function would check for the presence of the 'fileUrl' header and directly fetch content from the specified URL without restricting access to local filesystem paths. The lack of validation for URL schemes (like file://) and path restrictions enabled attackers to read arbitrary local files. This matches the CWE-200 pattern of exposing sensitive data through direct URL handling.
