High Risk!

We are checking vulnerabilities of the signature owner and we found that if you convert the nitro to excel or power point you can able to copy and reuse the signature along with it.

Hello @AFP Procurement,

Thank you for reaching out to us through our Community Forums and for the private message.

Did the owner use the 'Sign' tool under Protect Tab? If yes, converting it to a different file-type should not allow the signature to be converted into an image. I tested this with 13.49 and the resulting document does not have the signature in it.

To further troubleshoot this, kindly update to Nitro PDF Pro 13.49 using the installer from our page https://www.gonitro.com/nps/product-details/downloads and try again.

Thank you for choosing Nitro and I hope this helps.
