picklescan before 1.0.4 fails to block pkgutil.resolve_name, allowing attackers to bypass the entire blocklist by resolving any dangerous function through indirect REDUCE calls. Remote attackers can invoke any blocked function such as os.system, builtins.exec, or subprocess.call to achieve remote code execution.
picklescan < 1.0.4Upgrade to a patched release:
picklescan 1.0.4Connected by shared product, vendor, weakness, or advisory.
