Summary
mcp-server-kubernetes has potential security issue in execinpod tool
Impact
Command injection allows arbitrary command execution within Kubernetes pods through shell metacharacter interpretation.
- Command Injection: Shell metacharacters in string commands are interpreted, allowing command chaining and arbitrary command execution
- Data Access: Commands can access sensitive data within pods (secrets, configmaps, environment variables)
- Pod State Modification: Commands can modify pod state or install backdoors
- Indirect Prompt Injection: When combined with indirect prompt injection, AI agents may execute commands without explicit user intent
Untrusted input is inserted into a command that is later executed by the application, allowing the attacker to alter the intent of that command. Typical impact: arbitrary command execution in the application's environment.
CVE-2025-66404 has a CVSS score of 6.4 (Medium). The vector is network-reachable, high privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.9.8); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is CVE-2025-66404? CVE-2025-66404 is a medium-severity command injection vulnerability in mcp-server-kubernetes (npm), affecting versions <= 2.9.7. It is fixed in 2.9.8. Untrusted input is inserted into a command that is later executed by the application, allowing the attacker to alter the intent of that command.
- How severe is CVE-2025-66404? CVE-2025-66404 has a CVSS score of 6.4 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of mcp-server-kubernetes are affected by CVE-2025-66404? mcp-server-kubernetes (npm) versions <= 2.9.7 is affected.
- Is there a fix for CVE-2025-66404? Yes. CVE-2025-66404 is fixed in 2.9.8. Upgrade to this version or later.
- Is CVE-2025-66404 exploitable, and should I be worried? Whether CVE-2025-66404 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-66404 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2025-66404? Upgrade
mcp-server-kubernetesto 2.9.8 or later.
