Technical details

The import routes in ApostropheCMS invoke bigUploadMiddleware without early authorization, allowing unauthenticated requests to execute upload initialization, temporary file processing, and cleanup operations. Authentication is checked only after these operations complete, enabling attackers to perform file uploads and intermediate processing without valid credentials. This is fixed in ApostropheCMS 4.33.0 and import-export module 3.7.0.

Affected products

ApostropheCMS ApostropheCMS before 4.33.0
ApostropheCMS import-export before 3.7.0
