Vulnerability from github – Published: 2026-07-01 00:34 – Updated: 2026-07-01 00:34

Details

picklescan before 0.0.29 fails to detect the built-in Python trace.Trace.runctx function when used in pickle file reduce methods, allowing attackers to execute arbitrary code. Remote attackers can craft malicious pickle files with trace.Trace.runctx payloads that bypass picklescan detection and execute code upon pickle.load() invocation.

Severity

8.1 (High)
