This vulnerability allows an attacker to execute arbitrary code on a victim's machine by enticing them to open a specially crafted file.
An attacker can craft a malicious (Jamovi document) file containing a JavaScript payload embedded in a column’s name. When the victim opens that file using a vulnerable version of jamovi, the payload executes in the context of the victim’s machine.

While this is the primary known vulnerability, examining jamovi's overall security is essential. jamovi 0955 exploit
In version 0.9.5.5, an attacker who gains access to an unauthenticated jamovi instance (often found in CTF environments like HackTheBox's "Talkative" machine ) can use the built-in R editor to execute arbitrary system commands. Because jamovi is designed to run R code for data analysis, this "feature" can be abused to gain a reverse shell on the host system.
The statistical analysis community was abuzz recently with the discovery of an exploit in jamovi, a popular open-source statistical software package. Specifically, the exploit was found in version 0.9.5.5 of jamovi, sparking concerns about data integrity and security. In this blog post, we'll take a closer look at what happened, how the exploit works, and what it means for users of jamovi.
and narrowing the scope of what the server could execute without explicit user consent. This vulnerability allows an attacker to execute arbitrary
Evaluating jamovi's security relative to its alternatives provides valuable context.
The critical vulnerability in these legacy versions is an un-sanitized injection vulnerability. When researchers audited the code, they found that the application did not sanitize metadata inputs—specifically the column names within jamovi’s native .omv data file format.
The implications of this exploit are significant, particularly for researchers and organizations relying on jamovi for data analysis. If exploited, the vulnerability could lead to: The statistical analysis community was abuzz recently with
If you or your institution are currently utilizing legacy builds of jamovi, immediate steps must be taken to neutralize the risk of client-side compromise. 1. Upgrade to a Supported Version Data security and the online demo version - jamovi forum
Here is an analysis of how the security flaw operates, its technical mechanics, and how users must secure their environments. The Technical Root Cause
