Security hole addressed a risk to files that included a clickable URL on your cloud file sharing service. When someone opens the file and clicks on an embedded hyperlink, then they get sent to the website of a third-party website owner. The security flaw has now been patched by Google, but its discovery indicates that the vulnerability of cloud data when accessed via a link can allow “anyone who has the link” to access your private data. Google said that the flaw only affected a “small subset of file types” in Google Drive.
