Deeper analysis
CVE-2022-0557 is an OS command injection vulnerability, tracked under CWE-78, that affects the microweber/microweber package on Packagist in all versions prior to 1.2.11. The flaw received a CVSS 3.1 score of 7.2 and permits an attacker to execute arbitrary operating-system commands through the application.
An authenticated user with high privileges can exploit the issue over the network without user interaction. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the affected system, enabling remote code execution and potential full host compromise.
Public references point to a specific commit that resolves the injection flaw, and the project released version 1.2.11 to address it. Security advisories and the associated huntr.dev report therefore recommend upgrading to the patched release as the primary mitigation.
Public proof-of-concept exploits have been published on Exploit-DB and PacketStorm, yet the EPSS score has remained flat at 0.1686 with no material increase after disclosure.
