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.","state":0,"publishedAt":"2026-03-10T18:18:54.737+00:00","modifiedAt":"2026-10-07T08:10:00.2+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/OneUptime/oneuptime/releases/tag/10.0.21","https://github.com/OneUptime/oneuptime/security/advisories/GHSA-jw8q-gjvg-8w4q"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-30957","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-749"],"productCriteria":["cpe:2.3:a:hackerbay:oneuptime:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-03-10T18:18:54.737","lastModified":"2026-10-07T08:10:00.200"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
