• CVE-2025-68154: 12.99% estimated exploitation activity in the next 30 days; percentile 96.33 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The fsSize() function in systeminformation is vulnerable to OS Command Injection (CWE-78) on Windows systems. The optional drive parameter is directly concatenated into a PowerShell command without sanitization, allowing arbitrary command execution when user-controlled input reaches this function. Affected Platforms: Windows only CVSS Breakdown: - Attack Vector (AV:N): Network - if used in a web application/API - Attack Complexity (AC:H): High - requires application to pass user input to fsSize() - Privileges Required (PR:N): None - no authentication required at library level - User Interaction (UI:N): None - Scope (S:U): Unchanged - executes within Node.js process context - Confidentiality/Integrity/Availability (C:H/I:H/A:H): High impact if exploited Note: The actual exploitability depends on how applications use this function. If an application does not pass user-controlled input to fsSize(), it is not vulnerable. --- Details Vulnerable Code Location File:…

# Patch Next advisory brief: CVE-2025-68154

Advisory: systeminformation has a Command Injection vulnerability in fsSize() function on Windows
IDs: CVE-2025-68154, GHSA-wphj-fx3q-84ch
Record: https://patchnext.com/advisories/cve-2025-68154 (revision 2, source checked 26 Oct 2026, 12:41 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: systeminformation 5.27.14. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm systeminformation: affected < 5.27.14; fixed in 5.27.14

## Suggested inspection (read-only)
- `npm ls systeminformation --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on systeminformation.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
