CVE-2026-30308 identifies a critical design flaw in the HAI Build Code Generator, specifically in its automatic terminal command execution functionality. The tool provides two execution modes: 'Execute safe commands' where commands predicted by the underlying AI model as safe are run automatically, and 'Execute all commands' which requires user approval for commands flagged as potentially destructive. The vulnerability arises because the AI model's classification mechanism can be manipulated through prompt injection attacks. An attacker can embed malicious commands within a crafted input template that deceives the AI model into categorizing these commands as safe. Consequently, these malicious commands are executed without any user intervention or approval, leading to arbitrary command execution on the host system. This bypasses the intended security control designed to prevent destructive operations. The lack of a CVSS score indicates the vulnerability is newly published and not yet fully assessed. No patches or known exploits are currently available. The vulnerability exploits weaknesses in AI-based command safety classification, highlighting risks in relying on AI judgment for security-critical decisions. The attack vector requires the attacker to supply input to the code generator, which may be feasible in environments where user inputs or external data influence command generation. The absence of authentication or user interaction requirements for executing 'safe' commands increases the risk. This vulnerability could allow attackers to execute arbitrary commands, potentially leading to system compromise, data theft, or disruption of services.

The impact of CVE-2026-30308 is significant for organizations using the HAI Build Code Generator, especially those relying on its automatic command execution feature. Successful exploitation allows attackers to execute arbitrary terminal commands without user approval, potentially leading to full system compromise. This can result in unauthorized data access, data modification or destruction, installation of malware, lateral movement within networks, and disruption of critical services. Since the vulnerability exploits AI misclassification, it undermines trust in automated security controls and may lead to broader security policy failures. Organizations with automated build or deployment pipelines that integrate this tool are at risk of supply chain attacks or insider threat exploitation. The lack of known exploits in the wild suggests the vulnerability is not yet actively exploited, but the ease of bypassing user approval mechanisms indicates a high likelihood of future attacks. The scope includes any environment where the tool is used, including development, testing, and production systems. Confidentiality, integrity, and availability are all at risk, with potential cascading effects on organizational security posture and compliance obligations.

To mitigate CVE-2026-30308, organizations should first disable the 'Execute safe commands' automatic execution mode until a secure fix is available. Implement strict input validation and sanitization on all inputs to the HAI Build Code Generator to prevent injection of malicious payloads. Enhance the AI model's command classification by incorporating adversarial training and anomaly detection to better identify malicious commands. Introduce multi-factor user approval workflows for all command executions, regardless of AI classification, to prevent bypass. Restrict the privileges of the process executing commands to the minimum necessary, using sandboxing or containerization to limit potential damage. Monitor logs and command execution histories for unusual or unauthorized activities. Engage with the vendor or maintainers for patches or updates addressing this vulnerability. Additionally, conduct security reviews of AI-based automation tools to identify similar risks. Educate developers and operators about the risks of prompt injection and the importance of manual oversight in automated command execution.
