# CVE-2026-27728: OneUptime: OS Command Injection in Probe NetworkPathMonitor via unsanitized destination in traceroute exec()

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 2.6% , percentile 85: FIRST’s model estimates a 2.6% chance of exploitation activity in the next 30 days, higher than 85% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes @oneuptime/common (npm) < 10.0.7, fixed in 10.0.7 . Check your lockfile, including transitive dependencies.

## What it is

OneUptime is a solution for monitoring and managing online services. Prior to version 10.0.7, an OS command injection vulnerability in NetworkPathMonitor.performTraceroute() allows any authenticated project user to execute arbitrary operating system commands on the Probe server by injecting shell metacharacters into a monitor's destination field. Version 10.0.7 fixes the vulnerability.

## Affected packages

- npm `@oneuptime/common` < 10.0.7 → fixed: 10.0.7

## Affected products (CVE record)

- OneUptime oneuptime: < 10.0.7

## Severity

- GitHub_M CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 2.60% probability of exploitation activity in the next 30 days; percentile 85.
