CVE-2026-30311
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 · uneditedRidvay Code's command auto-approval module contains a critical OS command injection vulnerability that renders its whitelist security mechanism completely ineffective. The system relies on fragile regular expressions to parse command structures; while it attempts to intercept dangerous operations, it fails to account for standard Shell command substitution Ridvay Code (specifically$(...)and backticks ...). An attacker can construct a command such as git log --grep="$(malicious_command)", forcing Syntx to misidentify it as a safe git operation and automatically approve it. The underlying Shell prioritizes the execution of the malicious code injected within the arguments, resulting in Remote Code Execution without any user interaction.
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 · high confidenceRidvay Code's command auto-approval module uses regex-based whitelisting to validate git commands but fails to sanitize command substitution syntax $(...) and backticks. Attackers can embed malicious commands inside git arguments like --grep="$(malicious_command)", causing the whitelist to approve the command while the underlying shell executes the injected payload, resulting in unauthenticated remote code 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.
-
Identify Ridvay Code installation and versionLocate the Ridvay Code installation directory and check the package.json, setup.py, or version file for the auto-approval module. Common paths may include node_modules/ridvay-auto-approval or a vendor/ridvay directory. Run 'npm list ridvay-auto-approval' or 'pip show ridvay-auto-approval' if using package managers.Affected if The installed version is 0.1.1 or lower.
-
Verify auto-approval module is enabledCheck the Ridvay configuration files (such as .ridvayrc, ridvay.config.js, or settings.json) for entries enabling the auto-approval module or git command validation features.Affected if The auto-approval module is enabled and processing git commands.
-
Inspect the regex whitelist implementationLocate the source file implementing the git command validation, typically named something like whitelist.js, validator.js, or approval.js within the Ridvay module directory. Examine the regex pattern used for command validation.Affected if The validation uses regex-based whitelisting without explicit blocking of shell metacharacters.
-
Test for shell injection vulnerabilityIf you have access to the git command input flow, examine how arguments are processed. Look for code that passes git arguments to a shell execution function (such as exec(), system(), or child_process with shell: true) without sanitizing $() or backtick syntax.Affected if Git arguments containing $(...) or backtick expressions are passed to shell execution without filtering.
You are affected if Ridvay Auto Approval Module version 0.1.1 or lower is installed, the auto-approval feature is enabled, and git commands are processed through regex-based validation that does not block shell command substitution syntax.

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 dataImplement strict input sanitization that rejects or properly escapes shell metacharacters including $(...), `...`, and other command substitution syntax in all command arguments, or use shell-execution-safe APIs that avoid shell interpretation entirely.
