Seriously, people - please check the stuff you fetch more carefully

Security vendor Sonatype believes developers are failing to address the critical remote code execution (RCE) vulnerability in the Apache Struts 2 framework, based on recent downloads of the code.
The vulnerability, tracked as CVE-2023-50164, is rated 9.8 out of 10 in terms of CVSS severity. It is a logic bug in the framework's file upload feature: if an application uses Struts 2 to allow users to upload files to a server, those folks can abuse the vulnerability to save documents where they shouldn't be allowed to on that remote machine. Thus someone could, for instance, use the flaw to upload a webshell script to a web server, and access it to take control of or get a foothold on that system.
The consequences of successful exploitation could be hugely damaging: think data theft, malware infections, network intrusion, and that sort of thing.
