Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-61489 is a command injection vulnerability (CWE-77) affecting the shell_exec function in sonirico mcp-shell version 0.3.1. Published on 2026-01-07, it allows attackers to execute arbitrary commands by supplying a crafted command string. The vulnerability carries a CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N), indicating network accessibility with low attack complexity.
Unauthenticated remote attackers can exploit this vulnerability over the network without requiring user interaction or privileges. Exploitation involves crafting a malicious command string that triggers arbitrary command execution via shell_exec, potentially leading to limited impacts on confidentiality and integrity, such as unauthorized access to certain data or modifications, while availability remains unaffected.
Mitigation details and patches are referenced in the project's GitHub repository at https://github.com/sonirico/mcp-shell and the associated issue tracker at https://github.com/sonirico/mcp-shell/issues/4. Security practitioners should review these sources for updates, workarounds, or remediation steps specific to the affected version.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover command-construction flaws before deployment.
Input validation directly stops construction of commands from untrusted data containing special elements.
Secure engineering principles include proper neutralization and safe command construction practices.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development catches command-injection vulnerabilities before release.
Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
