Jamovi 0955 Exploit [ 2026 Release ]

For security researchers: Before claiming an exploit, confirm it across clean environments. PoC code that works on a system with pre-existing R libraries may not work on vanilla installs.
For open-source projects: Adopt a formal CVE request process early. Even if a report is false, requesting a CVE and then marking it as “disputed” or “rejected” creates an authoritative record that search engines can prioritize over rumors.
For users: Do not rely on a single vulnerability database. Check the vendor’s own security advisory page. In jamovi’s case, no official advisory ever confirmed the 0.9.5.5 exploit.

The Payload: Attackers embed JavaScript into a jamovi project file (.omv).

The Execution: When a user opens the tainted file, the JavaScript triggers automatically in the app's UI. The jamovi 0

The Escalation: Because jamovi uses an underlying R/Python environment, the JavaScript can bridge to the system shell.
