Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Picklescan是美国Matthieu Maitre个人开发者的一款扫描Pickle文件安全风险的静态分析工具。 Matthieu Maitre Picklescan 0.0.28之前版本存在反序列化注入漏洞，该漏洞源于未能检测在reduce方法中使用torch.utils.data.datapipes.utils.decoder.basichandlers的恶意pickle文件，导致攻击者可以绕过安全检查，在反序列化过程中嵌入未检测到的恶意代码，从而实现远程代码执行。
