CVE-2026-7066 is a medium-severity vulnerability affecting the choieastsea simple-openstack-mcp software. The vulnerability, identified specifically in the exec_openstack function of the server.py file, enables OS command injection, which could allow remote attackers to execute arbitrary commands on the server. The CVSS score assigned to this vulnerability is 6.9, indicating a medium level of severity that organizations should take seriously.
This vulnerability allows attackers to manipulate command inputs, leading to potential unauthorized access and control over the affected system. Given the nature of the vulnerability and its potential impact, it is imperative that organizations prioritize addressing this issue to mitigate risks.
The exploit for this vulnerability has been made public, meaning that there is a genuine risk of exploitation in the wild. Organizations utilizing the affected software should assess their exposure and take necessary steps to remediate the vulnerability. Continuous delivery approaches, like rolling releases, complicate the identification of affected versions, increasing the urgency for action.
Considering the potential for exploitation, organizations should prioritize patching immediately. Failure to address this vulnerability could lead to significant business impacts, including data breaches and operational disruptions.
Vulnerability Details
CVE-2026-7066 is characterized by an OS command injection vulnerability found in the simple-openstack-mcp project, specifically affecting versions up to commit 767b2f4a8154cca344344b9725537a58399e6036. The vulnerability is linked to the exec_openstack function within the server.py file. The vulnerability was reported to the project maintainers, but there has been no response indicating a resolution.
The vulnerability has a CVSS score of 6.9, indicating a medium severity level. The attack vector is classified as network-based, with low complexity and no authentication required. Confidentiality, integrity, and availability impacts are all rated as low, suggesting that while the risk is present, the immediate damage may be limited. However, the potential for remote exploitation necessitates prompt attention.
Technical Analysis
The root cause of CVE-2026-7066 lies in how the exec_openstack function processes command inputs without proper validation, allowing attackers to inject arbitrary commands. The attack vector is network-based, meaning that an attacker does not need to be physically present in the local network to exploit the vulnerability. The attack complexity is low, as it requires no special conditions or privileges, and no user interaction is necessary.
As for the impact on confidentiality, integrity, and availability, the vulnerability is rated low across the board. This indicates that while the attacker may gain some level of access, the overall system integrity and availability may not be severely compromised under normal circumstances.
Risk & Impact Analysis
Organizations using the choieastsea simple-openstack-mcp software should be aware of the real-world risks associated with CVE-2026-7066. The potential for remote exploitation presents a significant threat, especially for organizations that rely on this software for critical operations. The blast radius of an attack could extend beyond the immediate target, affecting other connected systems and data.
The urgency of addressing this vulnerability is underscored by its CVSS score of 6.9. Organizations should assess their security posture and include this vulnerability in their priority patch cycle. Regular vulnerability assessments and penetration testing can help identify similar weaknesses in the future.
