If a specific study requires legacy engines (such as Jamovi 0.9.5.5 or versions prior to 1.6.18) for replication compliance, implement these safety parameters:
The primary risk associated with older versions like 0.9.5.5 is a cross-site scripting (XSS) vulnerability. In early iterations, jamovi’s reliance on the ElectronJS framework made it susceptible to malicious code injection via column names.

Version 0.9.5.5 is outdated and lacks the security patches found in current releases. jamovi 0955 exploit
An attacker builds a standard JavaScript payload engineered to spawn system processes. Because Electron provides access to NodeJS functions, the attacker utilizes the child_process module: javascript
: The attacker crafts a valid dataset inside an .omv file but substitutes metadata fields (like column headers or analysis options) with functional JavaScript payloads.

The weaponized file is delivered to the target via email, a shared research repository, or a spear-phishing campaign. When the victim double-clicks the file to review the statistical data, Jamovi reads the payload structure. The application immediately renders the script in the UI canvas, triggering execution with the . Historical Context and Exploitation in the Wild
The vulnerability exists in the column-name field within the ElectronJS Framework used by jamovi.
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) If a specific study requires legacy engines (such
The core of the issue often lies in "improper input validation." When jamovi 0.9.5.5 processed certain data structures, it failed to properly sanitize them.
If a user downloads a malicious .omv file from an untrusted source and allows the embedded scripts to run natively, the software executes those routines with the same permissions as the local user. 2. Cross-Site Scripting (XSS) via ElectronJS
If a victim opens this file in a vulnerable version of Jamovi: An attacker builds a standard JavaScript payload engineered
Jamovi is a legitimate open-source statistical software package (based on R) used for data analysis, and “0955” does not correspond to a recognized version number (e.g., recent stable versions are 2.3, 2.4, 2.5). It’s possible that:
