# CVE-2026-71551: Super Productivity: Arbitrary OS Command Execution via IPC EXEC Handler with Persistent Whitelist

- Severity: CVSS 7.8 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 18.13.0
- Published: 2026-08-18 · Updated: 2026-08-21

## Affected

- super-productivity: fixed in 18.13.0

## Description

Super Productivity is an advanced todo list app with integrated timeboxing and time tracking capabilities. Prior to 18.13.0, the EXEC IPC handler in electron/ipc-handlers/exec.ts accepts a command string from the renderer through the IPC.EXEC channel and executes it with child_process.exec(). The electron/preload.ts bridge exposes window.ea.exec() to renderer code, including community plugins executed with new Function(), without requiring nodeExecution permission. A confirmation dialog protects only the first execution, its persistence checkbox is selected by default, and approved commands are stored in the ALLOWED_COMMANDS value in simpleSettings for silent later execution with the desktop account's privileges. This issue is fixed in version 18.13.0.

## What to do
