From a JDK perspective you need to make sure you run with the
latest secure baseline update for your version : for more info see
http://www.oracle.com/technetwork/java/javase/overview/security-2043272.html
The rest is application architecture for which I don't think we can or
should give advice.
This is not a support channel. These lists are for people contributing
source code to OpenJDK.

Hi,
The front-end generates a base64 encoded image of a graph and send it
to the backend to use it with pdfbox to create a pdf file.
Are there any security concerns with in particular this line
"BufferedImage bufImg = ImageIO.read(new
ByteArrayInputStream(imageByte));
“?
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Path("/pdfbox")
public void getChartsPdf(String base64ImageData) throws IOException{
PDDocument doc = null;
byte[] imageByte;
String base64Image = base64ImageData.split(",")[1];
BASE64Decoder decoder = new BASE64Decoder();

contentStream.beginText();
contentStream.setFont( font, 12 );
contentStream.moveTextPositionByAmount( 50, 700 );
contentStream.drawString("Timeline");
contentStream.endText();
contentStream.drawXObject(ximage, 20, 500,

contentStream.close();
doc.save("testCharts.pdf");
} catch (Exception e) {
System.err.println(e.getMessage());
} finally {
if (doc != null) {
doc.close();
}
}
}
