AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Command execution gives full C/I/A impact, but as a library flaw exploitation depends on the host app routing untrusted input into the vulnerable option, so AC:H.

ngrok v4.3.3 and 5.0.0-beta.2 is vulnerable to Command Injection.
AnalysisAI
Command injection in the ngrok Node.js package (npm) versions 4.3.3 and 5.0.0-beta.2 allows attackers to execute arbitrary OS commands on the host running the tunneling wrapper, achieving total loss of confidentiality, integrity, and availability (CVSS 8.8). The flaw stems from unsanitized input being passed to a shell when invoking the underlying ngrok binary. There is no public exploit identified as weaponized, though a reference gist appears to contain proof-of-concept material, and EPSS remains low at 0.21% with SSVC marking exploitation status as 'none'.
Technical ContextAI
The affected component is the popular 'ngrok' npm module - a Node.js wrapper that programmatically manages ngrok tunnels by shelling out to the native ngrok agent binary. CWE-77 (Improper Neutralization of Special Elements used in a Command) indicates that connection or configuration parameters (e.g., tunnel options, region, auth token, or binary path passed to the API) are concatenated into a shell command without sanitization, so shell metacharacters (;, |, `, $()) supplied through those parameters are interpreted by the operating system rather than treated as literal data. The CPE data is a placeholder ('cpe:2.3:a:n/a:n/a') and provides no additional product identification; the npmjs.com reference is the authoritative anchor confirming this is the JavaScript package rather than the standalone ngrok agent itself.
RemediationAI
No vendor-released fixed version is identified in the provided data at time of analysis, so the primary action is to review the npm advisory and package release notes on https://www.npmjs.com for the ngrok package and upgrade to a patched release once published; do not rely on the 5.0.0-beta.2 pre-release. As compensating controls until a fix is confirmed, never pass user- or attacker-controlled input into ngrok API options (tunnel names, region, addr, binary path, or auth strings) - hardcode or strictly allowlist these values, which removes the injection vector at the cost of losing dynamic per-request tunnel configuration. If dynamic values are unavoidable, validate them against a strict character allowlist (e.g., alphanumerics only) to reject shell metacharacters, and run the Node process under a low-privilege, sandboxed account to limit the blast radius of any successful injection.
