The Content-Security-Policy header value is made up of one or more directives (defined below), multiple directives are separated with a semicolon The term Content Security Policy is often abbreviated as CSP.ĬSP was first designed to reduce the attack surface of Cross Site Scripting (XSS) attacks, later versions of the spec also protect against other forms of attack such as Click Jacking. The Content-Security-Policy header allows you to restrict which resources (such as JavaScript, CSS, Images, etc.) can be loaded, and the URLs that they can be loaded from.Īlthough it is primarily used as a HTTP response header, you can also apply it via a meta tag. What is Content-Security-Policy?Ĭontent-Security-Policy is the name of a HTTP response header that modern browsers use to enhance the security of the document (or web page). (It used to happen quit a bit during covid when some AV/blocker staff were slower than usual to update their definitions and whitelists).The new Content-Security-Policy HTTP response header helps you reduce XSS risks on modern browsers by declaring which dynamic resources are allowed to load.

When I tried to go to - all I got was no more When I clicked on the download free CCleaner icon - I got a full screen error message from UBlock Origin telling me it was stopping an unwanted tracker. I do this because the CCleaner updates don't work when I do it from the "Update Now" alerting program prompt. So, this morning I tried to go to to start a re-download from the website. Last night I got the CCleaner needs to update pop-up box. No issues unless I paid for the software.
