Glances: Insecure Pickle Deserialization in Version Cache Leads to Arbitrary Code Execution_CVE-2026-46607

{
    "lastseen": "",
    "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 Prior to 4.5.5, glances/outdated.py uses pickle.load() to read a version-check cache file stored at a predictable, world-accessible path (~/.cache/glances/glances-version.db or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 \u2014 through any of several realistic local or container-level scenarios \u2014 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.",
