CVE-2026-64955
MediumCVSS 6.1Exploitation Probability (EPSS)
Low risk29th percentile - higher than 29% of all known CVEs
Summary
Velociraptor fails to sanitize data when exporting to CSV, which can lead to formula execution by Microsoft Excel during import. Cells starting with certain characters are treated as formulas, allowing arbitrary code execution.
Risk Assessment
A user opening an exported CSV file in Excel may trigger malicious formulas, potentially leading to compromise of the user's system.
Recommendation
Apply Velociraptor updates if available, or consider adding data sanitization mechanisms before CSV export.
Original NVD description (English source)
When Microsoft Excel imports a CSV file, it executes cells beginning with certain characters as formulas, giving such CSV files arbitrary execution. Velociraptor fails to sanitize such cells when exporting to CSV from various places such as the GUI, offline collector or data exports. 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. However, since this is such a common use case for Velociraptor we decided to highlight it in an advisory.
