Picklescan Bypasses Unsafe Globals Check using pty.spawn

SummaryThe vulnerability allows malicious actors to bypass PickleScan's unsafe globals check, leading to potential arbitrary code execution. The issue stems from the absence of the pty library more specifically, of the pty.spawn function from PickleScan's list of unsafe globals. This vulnerabilit...
