CVE-2019-11244 describes a vulnerability in Kubernetes versions 1.8.x-1.14.x where kubectl caches schema information with world-writeable permissions in the user's home directory or a specified cache directory. This allows other local users or groups to modify these cached files, potentially disrupting kubectl operations. The vulnerability has a CVSS score of 5.0 (Medium), indicating a local attack vector with low complexity, requiring user interaction, and leading to high integrity impact without confidentiality or availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
