Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- A successful exploit gives an attacker total control of the affected component, not partial access.

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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-71551 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-71551 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-71551. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
