CVE-2026-64955
NVD: When Microsoft Excel imports a CSV file, it executes cells beginning with certain characters as formulas, giving such CSV files arbitrary execution. NVD: Velociraptor fails to sanitize such cells when exporting to CSV from various places such as the GUI, offline collector or data exports. NVD: It is not clear if the vulnerability is actually in Microsoft Excel treating a CSV data file as executable content, or if Velociraptor should be sanitizing the data to prevent Excel from executing it.
