CVE-2025-71345

picklescan before 0.0.30 fails to detect malicious pickle files that invoke torch.utils.bottleneck.main.runautogradprof function. Attackers can embed undetected code in pickle files that executes during deserialization, enabling remote code execution...

CVE-2025-71343

picklescan before 0.0.30 fails to detect malicious pickle files that exploit lib2to3.pgen2.pgen.ParserGenerator.makelabel function in the reduce method. Attackers can craft malicious pickle files with embedded code that evades detection but executes arbitrary commands when pickle.load is called...

CVE-2025-71368

picklescan before 0.0.30 fails to detect the doctest.debugscript function when analyzing pickle files, allowing attackers to execute arbitrary code.
