Issue descriptionVERSION Chrome Version: 56.0.2924.87 + stable Operating System: MS Windows 10 REPRODUCTION CASE Dear Support, I was able to break the security of a pdf file easily (without buying any additional software and without using any cracking tool). as you can see in the attachments, the security properties was changed from: Acrobat Security Before.png to: Acrobat Security After.png How? I opened Google Chrome and dragged the pdf file into it and the file was opened in chrome. Then I went to the menu of Chrome and clicked on Print and selected Save As PDF, and I got the non-secured version. I contacted Adobe about it and they recommended to contact you. Best Regards, Mohammed Al-Shehri

Mechanisms to bypass the "Document Restrictions" feature of Adobe Acrobat are numerous; printing to Chrome's "Save as PDF" feature is only one of many. This does not represent a security vulnerability in Chrome.

Dear Support, Thank you very much for your reply. Please note that I am not getting this issue in other browsers (like IE or Firefox), but I am facing it in Chrome! I conferred with Adobe on this issue, and you may reach out to psirt@adobe.com to discuss that issue further (if needed). Best Regards, Mohammed Al-Shehri

Neither Internet Explorer nor Firefox includes a PDF generation engine.
Windows 10 does include one ("Microsoft Print to PDF") and it too allows users to print a restricted PDF to a new PDF without the restrictions.
