File creation and deletion via missing permission checks
Published Mar 6, 2026 · Updated Mar 6, 2026
Incorrect authorization in Parse Server before 8.6.5 and 9.0.0 through 9.5.0-alpha.2 allows remote authenticated users to write or delete files. The Files API upload and delete handlers accept readOnlyMasterKey authorization without enforcing write permission. Exploitation requires possession of that key and network access to the Files API, enabling arbitrary file uploads or deletion of stored files.
