Of the three new Spring framework vulnerabilities, one of them (Spring4Shell) sounds worryingly similar to the recent high-severity exploit, Log4Shell. While the vulnerabilities discovered in the Spring framework do have some things in common with Log4Shell, there are also significant differences impacting how we should respond. Of the three Spring vulnerabilities, two are critical, allowing for remote code execution (RCE), while the third is a denial-of-service vulnerability.
