CVE-2022-40764Public exploitNetwork attack vector

Arbitrary command execution via shell-enabled child process

Published Oct 3, 2022 · Updated Aug 3, 2024

Command injection in Snyk CLI before 1.996.0 allows attackers to execute arbitrary commands by scanning untrusted Go project files. The snyk-go-plugin passes arguments derived from vendor/vendor.json to a child process with shell execution enabled, allowing shell metacharacters to become commands. Execution requires snyk test or an IDE or CI integration to scan a crafted project, and injected commands run with the scanner process's privileges.
