Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Nicolas Hennion Glances是Nicolas Hennion个人开发者的一款系统监控工具。 Nicolas Hennion Glances 4.5.5之前版本存在反序列化注入漏洞，该漏洞源于outdated.py使用pickle.load()从可预测且全局可访问的路径读取版本检查缓存文件，且未进行完整性检查、签名验证或格式验证，可能导致具有写入权限的攻击者放置恶意pickle文件，在下次启动时实现任意代码执行。

Vulnerability Title
Glances: Insecure Pickle Deserialization in Version Cache Leads to Arbitrary Code Execution
Source: CVE Program / CVE List V5
Vulnerability Description
Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.5, glances/outdated.py uses pickle.load() to read a version-check cache file stored at a predictable, world-accessible path (~/.cache/glances/glances-version.db or $XDG_CACHE_HOME/glances/glances-version.db). No integrity check, signature verification, or format validation is performed before deserialization. An attacker with write access to that path — through any of several realistic local or container-level scenarios — can plant a malicious pickle file and achieve arbitrary code execution as the OS user running Glances the next time it starts with version checking enabled (the default). This vulnerability is fixed in 4.5.5.
