OneUptime is a solution for monitoring and managing online services. Prior to 10.0.21, OneUptime Synthetic Monitors allow a low-privileged authenticated project user to execute arbitrary commands on the oneuptime-probe server/container. The root cause is that untrusted Synthetic Monitor code is executed inside Node's vm while live host-realm Playwright browser and page objects are exposed to it. A malicious user can call Playwright APIs on the injected browser object and cause the probe to spawn an attacker-controlled executable. This is a server-side remote code execution issue. It does not require a separate vm sandbox escape. This vulnerability is fixed in 10.0.21.

 https://cve.radiocsirt.org/vuln/ghsa-jw8q-gjvg-8w4q GHSA-jw8q-gjvg-8w4q — OneUptime has Synthetic Monitor RCE via exposed Playwright browser object 2026-10-07T00:52:18.889639+00:00

Affected: npm: @oneuptime/common

### Summary

OneUptime Synthetic Monitors allow a low-privileged authenticated project user to execute arbitrary commands on the `oneuptime-probe` server/container.

The root cause is that untrusted Synthetic Monitor code is executed inside Node's `vm` while live host-realm Playwright `browser` and `page` objects are exposed to it. A malicious user can call Playwright APIs on the injected `browser` object and cause the probe to spawn an attacker-controlled executable.

This is a server-side remote code execution issue. It does not require a separate `vm` sandbox escape.

## Details

A normal project member can create or edit monitors and monitor tests:

- `Monitor` access control: https://github.com/OneUptime/oneuptime/blob/707bfd62e721a2845ee05b87cb5d3c611bda2276/Common/Models/DatabaseModels/Monitor.ts#L45-L70 - `MonitorTest` access control: https://github.com/OneUptime/oneuptime/blob/707bfd62e721a2845ee05b87cb5d3c611bda2276/Common/Models/DatabaseModels/MonitorTest.ts#L27-L52

The dashboard exposes a Playwright code editor for Synthetic Monitors and allows a user to queue a test run:
