Announcing JavaScript & HTML Policies for PDF Content Verification
10/16/2023 - Brian O'Neill


We are pleased to announce that the list of content verification policies available to Storage Protect & Shield customers has been expanded with the release of version 8-2-8 of the Cloudmersive Virus Scan API.

Through the permitJavascriptAndHtmlinPDFs request parameter, customers can now set restrictions against PDFs containing JavaScript or HTML code. When this policy is active, files with .PDF extensions that contain HTML or JavaScript within their file structure will fail their content verification check and trigger a CleanResult: False response.

Malicious PDF files containing JavaScript and HTML can be used to bypass virus & malware scanning policies, and this can leave internal or external network users at risk of inadvertently accessing malicious content and initiating a cyberattack. The option to categorically restrict PDF files containing JavaScript and HTML is another convenient custom-content threat prevention solution for customers with multi-pronged content security concerns.

In addition to gaining state-of-the-art, zero-day file threat detection capabilities with their baseline Cloudmersive Virus Scan API product, customers utilizing the Advanced Virus Scan API service (through any deployment type) can easily block executables, invalid files, scripts, password-protected files, and more using simple custom request parameters.
