How can I prevent the user from change the extension name of attachments
Hi Team
In my application the user can attach files ex (gif , png , pdf) to work object.
I'm using CallVirusCheck , it's working fine, but the issue is when the user trying to change the extension name of the file (for example the name of file is "https" and the type of the file is "docx" when the user change the extension name to "pdf " ) <<please see attach "change" and "after change"
the validation it's not working and the system accepts not allowed types of attachments <<please see attach "after attach".how can i solve this issue ?
