Technical details
The vulnerability exists in the API attachment upload flow: when attachments are created via API with base64-encoded data, the AttachmentSubmitHandler processes the data without enforcing the configured MAX_ATTACHMENT_FILE_SIZE limit. Normal browser-based uploads are validated at the Symfony form layer, but the API base64 path bypasses this check. An authenticated API user with attachment creation permissions can submit oversized base64-encoded files, which the application will decode and store, potentially causing denial of service.
