HIGH CVSS 8.1 Exploit Available

Published: July 4, 2026 | Last Modified: July 4, 2026

Description

picklescan before 0.0.30 fails to detect the asyncio.unix_events._UnixSubprocessTransport._start function in pickle reduce methods, allowing remote code execution. Attackers can craft malicious pickle files embedding this built-in function that evade detection but execute arbitrary commands when loaded.
