先是在野0day 《Grafana未授权任意文件读取》传出，随后更劲爆的《Apache Log4j2远程代码执行》的POC、EXP相继出现，后者的payloads传播速度之快、以及影响范围之广，使其在业内堪称 “核弹级” 漏洞。

We?re proud to announce the 1.0 release of the Property Manager extension to Visual Studio Code and Eclipse. With the new Property Manager extension, you can edit and validate Property Manager API (PAPI) JSON rule trees right from your integrated development environment (IDE). It allows you to make and validate critical changes to your configuration closer to your DevOps environment. Once you've updated and validated the configuration file in your IDE, you can easily push it back to the platform with PAPI or Akamai command-line interface (CLI).
