CVE-2026-12555 is an insecure temporary-file handling vulnerability in HP Easy Start for macOS before 2.16.7.260722. The HP Uninstaller used predictable temporary-file locations while executing with administrator privileges. A local attacker could prepare a symbolic link at an expected temporary-file location; once a user authorizes the uninstaller, the privileged process may follow that link when writing generated log data to an attacker-selected file.
