CVE-2026-2178 is a command injection vulnerability found in the r-huijts xcode-mcp-server, affecting the registerXcodeTools function in the src/tools/xcode/index.ts file of the run_lldb component. The vulnerability arises from improper sanitization or validation of the args argument, which an attacker can manipulate remotely to execute arbitrary commands on the underlying system. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), no privileges (PR:L) beyond low-level access, and no user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a low level but can be escalated depending on the commands executed. The product follows a rolling release model, making it difficult to specify affected versions precisely, but the vulnerability exists up to commit f3419f00117aa9949e326f78cc940166c88f18cb. A patch identified by commit 11f8d6bacadd153beee649f92a78a9dad761f56f addresses the issue. Although no known exploits in the wild have been reported, the exploit code is publicly available, increasing the risk of exploitation. The vulnerability's CVSS 4.0 base score is 5.3, indicating a medium severity level. The vulnerability is significant for environments where xcode-mcp-server is used, especially in continuous integration and development pipelines, as it can allow attackers to execute arbitrary commands remotely, potentially leading to system compromise or lateral movement within networks.

For European organizations, the impact of CVE-2026-2178 can be substantial, particularly for those relying on the r-huijts xcode-mcp-server in software development, continuous integration, and deployment environments. Successful exploitation could lead to unauthorized command execution, resulting in data breaches, system manipulation, or disruption of development pipelines. This could compromise intellectual property, delay software releases, and damage organizational reputation. The vulnerability's remote exploitability without user interaction increases the risk of automated attacks. Organizations in sectors with high software development activity, such as technology firms, financial institutions, and research centers, are particularly vulnerable. Additionally, if the compromised systems have network access to sensitive internal resources, attackers could pivot to more critical infrastructure. The medium severity rating suggests the threat is serious but not immediately critical, allowing some time for mitigation if addressed promptly.

To mitigate CVE-2026-2178, European organizations should: 1) Apply the patch identified by commit 11f8d6bacadd153beee649f92a78a9dad761f56f as soon as possible to eliminate the vulnerability. 2) Restrict network access to the xcode-mcp-server service using firewalls or network segmentation to limit exposure to trusted hosts only. 3) Implement strict input validation and sanitization on any interfaces interacting with the registerXcodeTools function if custom modifications exist. 4) Monitor logs and system behavior for unusual command execution patterns or unexpected process spawning that could indicate exploitation attempts. 5) Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection signatures. 6) Conduct regular security audits and code reviews of development tools and CI/CD pipelines to identify similar vulnerabilities. 7) Educate development and operations teams about the risks of command injection and secure coding practices. 8) Maintain an up-to-date asset inventory to quickly identify affected systems given the rolling release nature of the product.
