Summary

CVE-2026-30308 is a critical-severity Code Injection (CWE-94) vulnerability in Presidio Hai Build. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

This vulnerability is AI-related — categorised as LLM Application Platforms; in the LLM/Generative AI Risks risk domain.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-30308 is a critical vulnerability in the HAI Build Code Generator, a tool that supports automatic terminal command execution with two modes: "Execute safe commands" and "Execute all commands." In the safe mode, a model evaluates commands, automatically executing those deemed safe while requiring user approval for potentially destructive ones. The flaw stems from this design's susceptibility to prompt injection attacks (CWE-94), where attackers can craft inputs to trick the model into misclassifying malicious commands as safe, bypassing approval entirely.

The vulnerability enables remote attackers with no privileges or user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, score 9.8) to achieve arbitrary command execution on the target's system. By using a generic template to wrap malicious payloads, an attacker can mislead the model during command generation or processing, leading to unauthorized execution of destructive actions such as data exfiltration, system compromise, or further persistence.

Mitigation details and advisories are available in the referenced sources, including the GitHub issue at https://github.com/Secsys-FDU/LLM-Tool-Calling-CVEs/issues/10 and the project repository at https://github.com/presidio-oss/hai-build. Security practitioners should review these for patches, workarounds, or updated configurations to address the prompt injection risk.

executed, whereas if the model judges a command to be potentially destructive, it still requires user approval. However, this design is highly susceptible to prompt injection attacks. An attacker can employ a generic template to wrap any malicious command and mislead the model into misclassifying it as a 'safe' command, thereby bypassing the user approval requirement and resulting in arbitrary command execution.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
