CVE-2026-8663: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Rapid7 InsightConnect RPM Plugin
CVE-2026-8663 is an OS Command Injection vulnerability in the Rapid7 InsightConnect RPM Plugin on Linux. It allows authenticated users to execute arbitrary operating system commands by exploiting insufficient input sanitization in the parameters repo, key, or name used in shell command construction. The vulnerability has a CVSS 3.1 base score of 6.0, indicating medium severity. No specific affected versions or patches have been disclosed yet.
AI Analysis
Technical Summary
This vulnerability arises from improper neutralization of special elements in OS commands (CWE-78) within the Rapid7 InsightConnect RPM Plugin on Linux. Authenticated attackers can leverage the repo, key, or name parameters to inject arbitrary OS commands due to inadequate input sanitization during shell command construction. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, low confidentiality impact, high integrity impact, and low availability impact. No vendor advisory or patch information is currently available.
Potential Impact
An authenticated attacker with high privileges can execute arbitrary OS commands on the affected system, potentially leading to unauthorized modification of data (high integrity impact) and limited confidentiality and availability impacts. This could allow attackers to alter system behavior or compromise system integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the InsightConnect RPM Plugin to trusted users only and monitor for suspicious activity related to command execution. Avoid exposing the vulnerable parameters to untrusted input.
