Detailsinfo

A vulnerability was found in Rapid7 Velociraptor up to 0.77.1. It has been classified as very critical. This affects an unknown functionality of the component CSV file Handler. The manipulation with an unknown input leads to a csv injection vulnerability. CWE is classifying the issue as CWE-1236. The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at docs.velociraptor.app. This vulnerability is uniquely identified as CVE-2026-64955 since 07/21/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/12/2026).
