jamovi is a community-driven statistical spreadsheet software built on top of the R programming language. Version 0.9.5.5 was an early iteration that aimed to simplify data analysis through a rich graphical user interface (GUI). Because jamovi bridges the gap between a user-friendly interface and a powerful R backend, it requires a high degree of integration between its UI components and its execution engine. The Vulnerability: Remote Code Execution (RCE)

The exploit relies on a combination of factors, including:

When an older version of Jamovi parses this file and displays the spreadsheet UI, it fails to sanitize the column name string. The application reads the raw script tags and executes the code with the full local privileges of the active desktop user.

Leaving an old 0.9.5.5 deployment on any system creates a clear point of failure. Secure your research infrastructure by implementing these defensive steps: 1. Upgrade Immediately

Configure your Endpoint Detection and Response (EDR) agents to flag anomalous parent-child process trees. For example, any instance where jamovi.exe spawns cmd.exe , powershell.exe , or bash should instantly trigger an alert and isolate the host device.
