CVE-2026-8660
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOS Command Injection vulnerability in the ping action of Rapid7 InsightConnect Ping Plugin on Linux allows remote attackers to execute arbitrary OS commands via the host parameter due to insufficient input validation when constructing shell commands.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Rapid7 InsightConnect Ping Plugin on Linux contains an OS command injection vulnerability in its ping action. The host parameter is not properly validated or sanitized before being incorporated into a shell command, allowing an attacker to inject arbitrary OS commands. A remote attacker can craft malicious input in the host parameter to break out of the intended ping command and execute arbitrary commands on the underlying Linux system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm InsightConnect is installedLocate the Rapid7 InsightConnect installation directory. On Linux systems, this is typically found under /opt/insightconnect or /usr/local/insightconnect. Check for the presence of the insightconnect service or CLI tools.Affected if InsightConnect is not installed on the system.
-
Locate the ping pluginNavigate to the plugin directory within the InsightConnect installation. Ping plugins are typically stored under plugins/ or lib/ subdirectories. Search for directories or files containing 'ping' in the name.Affected if The ping plugin is not present in the installation.
-
Identify the ping plugin versionExamine the plugin manifest file (often named manifest.json, plugin.yaml, or VERSION) located within the ping plugin directory. Read the version field from this file.Affected if The version is lower than 1.0.4.
-
Verify the operating systemRun the command 'uname -s' or check /etc/os-release to confirm the underlying operating system is Linux. The vulnerability only affects the Linux version of the plugin.Affected if The operating system is not Linux.
-
Check if ping action is configuredReview the workflow or automation configurations within InsightConnect that utilize the ping action. Look for workflows or triggers that invoke the ping plugin with user-supplied host parameters.Affected if The ping action is actively used with external or user-controlled host input.
A system is affected if it runs Rapid7 InsightConnect with the ping plugin version below 1.0.4 on Linux and has the ping action configured with external host input.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.0.4
Implement strict input validation and use parameterized command execution (e.g., passing arguments safely rather than shell string concatenation) to ensure the host parameter cannot contain shell metacharacters or command separators.
1.0.4
- 1. Access the InsightConnect platform administration interface
- 2. Navigate to the Plugins or Integrations section
- 3. Locate the Ping plugin in the list of installed plugins
- 4. Check the current installed version of the Ping plugin
- 5. If version is below 1.0.4, locate the upgrade option for the Ping plugin
- 6. Initiate the upgrade to version 1.0.4
- 7. Verify the upgrade completed successfully by confirming the new version number
- 8. Test the Ping functionality to ensure the plugin operates correctly after the upgrade
