CVE-2023-54345 affects Frappe Framework ERPNext 13.4.0, containing a sandbox escape vulnerability in RestrictedPython. Authenticated users with System Manager role can execute arbitrary code by exploiting frame introspection. Attackers create server scripts via /app/server-script endpoint and access gi_frame attribute to traverse the call stack. This allows invoking os.popen to execute system commands, effectively bypassing security restrictions. The vulnerability represents a significant privilege escalation risk in ERPNext deployments.
