Overview
@evomap/evolver is an A GEP-powered self-evolution engine for AI agents. Features automated log analysis and Genome Evolution Protocol (GEP) for auditable, reusable evolution assets.
Affected versions of this package are vulnerable to Command Injection via the _extractLLM function. An attacker can execute arbitrary shell commands on the server by supplying crafted input to the corpus parameter, which is incorporated into a shell command without proper sanitization and executed using execSync. This can result in full system compromise, data exfiltration, or installation of malware by injecting shell metacharacters or command substitution syntax.
