CVE-2026-30308
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn its design for automatic terminal command execution, HAI Build Code Generator offers two options: Execute safe commands and Execute all commands. The description for the former states that commands determined by the model to be safe will be automatically 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceHAI Build Code Generator's automatic command execution feature uses an LLM to classify commands as 'safe' or requiring approval. The vulnerability allows attackers to use prompt injection templates to wrap malicious commands, causing the model to misclassify them as safe and bypass user approval, enabling arbitrary OS command execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Presidio Hai Build installationLocate the HAI Build Code Generator installation directory and identify the executable or service running the productAffected if Presidio Hai Build is present on the system
-
Check installed versionRun 'hai-build --version' or inspect the product's about/info panel to determine the exact version numberAffected if Version is 3.13.3 or lower
-
Verify automatic command execution is enabledInspect the product configuration settings for 'automatic command execution', 'auto-approve', or 'LLM-based command classification' featuresAffected if The automatic command execution feature with LLM classification is turned on
-
Examine command execution logsReview command execution audit logs for entries showing commands classified as 'safe' that contain unusual patterns (wrapping characters, instruction text mixed with commands)Affected if Logs show commands that bypassed approval despite containing injection-style patterns
-
Inspect command input handlingCheck if the system accepts raw command input through API, CLI, or UI without structured input parsing that separates instruction text from argumentsAffected if User-provided commands are passed directly to the LLM without input separation or validation
A user is affected if Presodio Hai Build version 3.13.3 or lower is installed with the automatic LLM-based command classification feature enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRedesign command classification to use structured input parsing that separates command arguments from instruction text, implement input validation to detect injection patterns, and require additional verification layers before executing any dynamically constructed commands.
