Open-source software is everywhere now, but the Log4j flaw that affects Java enterprise applications is a reminder of what can go wrong in the complicated modern software supply chain.

There are 17,000 unpatched Log4j packages in the Maven Central ecosystem, leaving massive supply-chain risk on the table from Log4Shell exploits.

Why you may already be at risk, how to detect and mitigate the Log4j vulnerabilities now, and how to improve your code security in the future.

A serious code execution vulnerability in Log4j has security experts warning of potentially catastrophic consequences for enterprise organizations and web apps.

Ditch Log4j 2.15: DNS exfiltration & RCE possible Log4j 2.15.0 might contain even more severe vulnerabilities than the ones discovered so far, which is why 2.16.0 is by far a safer bet.

A bug in the ubiquitous Log4j library can allow an attacker to execute arbitrary code on any system that uses Log4j to write logs. Does yours?

A sure-fire way to prevent exploitation of Log4j vulnerabilities has yet to appear, but these actions are your best bet for reducing risk.
