CVE-2018-6342
Last modified
CVE-2018-6342 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. react-dev-utils on Windows allows developers to run a local webserver for accepting various commands, including a command to launch an editor. The input to that command was not properly sanitized, allowing an attacker who can make a network request to the server (either via CSRF or by direct request) to execute arbitrary commands on the targeted system. EPSS estimates a 2.84% chance of exploitation in the next 30 days.
