Security company Oligo is warning that hackers can bypass firewalls and gain full access to local networks with the help of a bug found in most browsers for macOS and Linux. According to Oligo, the bug has been around for 18 years and all the hackers have to do is use the 0.0.0.0 address instead of 127.0.0.1.
Recently, more and more hackers have started exploiting the bug; updates to block the 0.0.0.0 address are on the way for Safari, Firefox, Chrome and Edge.
Note: the bug is not found in browsers for Windows.
