CVE-2026-8659 Overview
CVE-2026-8659 is an OS command injection vulnerability affecting the Rapid7 InsightConnect SQLmap Plugin on Linux. Authenticated attackers can execute arbitrary operating system commands by injecting payloads into the api_host or api_port parameters during connection configuration. The flaw stems from insufficient input validation when these parameters are passed to underlying shell operations. The weakness is classified under [CWE-78] (Improper Neutralization of Special Elements used in an OS Command).
Critical Impact
An authenticated attacker with high privileges can execute arbitrary commands on the host running the InsightConnect SQLmap Plugin, leading to integrity compromise of the orchestration environment.
Affected Products
- Rapid7 InsightConnect SQLmap Plugin
- Linux-based InsightConnect orchestration hosts running the affected plugin

Technical Details for CVE-2026-8659
Vulnerability Analysis
The vulnerability resides in the connection configuration logic of the Rapid7 InsightConnect SQLmap Plugin. When a user configures a connection, the plugin accepts an api_host and api_port value intended to identify the SQLmap API endpoint. The plugin passes these values into an OS-level command without proper neutralization of shell metacharacters. An authenticated attacker who can configure or modify a plugin connection can append shell operators such as ;, |, &&, or backticks to inject additional commands. Because the plugin executes on the InsightConnect orchestrator host, command execution occurs in the context of the plugin runtime on Linux. The result is arbitrary command execution that primarily affects integrity, with limited confidentiality and availability impact according to the published CVSS metrics.
Root Cause
The root cause is improper neutralization of special elements used in an OS command [CWE-78]. The plugin concatenates attacker-controlled api_host and api_port strings into a command string rather than passing them as isolated arguments to a process API. No allowlist validation, escaping, or strict type checking restricts the input to legitimate hostnames or numeric ports.
Attack Vector
Exploitation requires authenticated access with privileges sufficient to create or edit a SQLmap plugin connection within InsightConnect. The attacker supplies a crafted value such as a hostname appended with a shell separator and a follow-on command. When the plugin invokes SQLmap with that configuration, the injected command executes on the underlying Linux host. No user interaction is required beyond the attacker's own authenticated session, and the attack is performed over the network.
No verified public proof-of-concept code is available. Refer to the Rapid7 SQLMap Extension for plugin documentation and updates.
Detection Methods for CVE-2026-8659
Indicators of Compromise
- Unexpected child processes spawned by the InsightConnect plugin runtime on Linux orchestrator hosts
- Plugin connection records containing shell metacharacters (;, |, &, `, $()) in api_host or api_port fields
- Outbound network connections from the orchestrator host to attacker-controlled infrastructure shortly after a SQLmap plugin job runs
Detection Strategies
- Inspect InsightConnect audit logs for connection configuration changes that include non-alphanumeric characters in api_host or api_port
- Hunt for anomalous process lineage where the SQLmap plugin process is the parent of shells (/bin/sh, /bin/bash), curl, wget, or nc
- Correlate plugin execution timestamps with new persistence artifacts such as cron entries, SSH keys, or systemd units on the host
Monitoring Recommendations
- Enable detailed process and command-line auditing on Linux hosts running InsightConnect plugins via auditd or eBPF-based sensors
- Forward orchestrator host telemetry and InsightConnect application logs into a centralized analytics platform for correlation
- Alert on any plugin connection modification performed by accounts that do not typically administer integrations
How to Mitigate CVE-2026-8659
Immediate Actions Required
- Update the Rapid7 InsightConnect SQLmap Plugin to the latest version available from the Rapid7 SQLMap Extension catalog
- Restrict the InsightConnect role permissions that allow plugin connection creation and modification to a minimum set of trusted administrators
- Review all existing SQLmap plugin connections for unexpected characters or values in api_host and api_port
- Rotate credentials and API keys stored within InsightConnect if tampering with plugin connections is suspected
Patch Information
Apply the latest version of the SQLmap plugin published by Rapid7. Confirm the installed plugin version against the vendor's extension page and redeploy any workflows that use the updated connection schema. Validate that the patched plugin properly escapes or argument-isolates the api_host and api_port fields.
Workarounds
- Disable or remove the SQLmap plugin from InsightConnect workflows until a patched version is deployed
- Constrain access to the InsightConnect orchestrator host using network segmentation and host-based firewalls
- Enforce strict review of any workflow that accepts user-supplied input flowing into plugin connection parameters
- Run the orchestrator under a least-privileged service account to limit the blast radius of command execution
