CVE-2024-21574
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 · uneditedThe issue stems from a missing validation of the pip field in a POST request sent to the /customnode/install endpoint used to install custom nodes which is added to the server by the extension. This allows an attacker to craft a request that triggers a pip install on a user controlled package or URL, resulting in remote code execution (RCE) on the server.
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 confidenceThe /customnode/install endpoint in the extension fails to validate the 'pip' field in POST requests. An attacker can supply arbitrary package names or URLs to pip install, which executes pre-install and post-install scripts within packages, allowing full remote code execution on the server.

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 /customnode/install endpoint existsReview your web server logs or route configuration for requests to /customnode/install or /api/customnode/install. Use 'grep -r "customnode/install"' or equivalent in your source/routes directory.Affected if The endpoint is present and exposed in your environment
-
Identify the pip field handling codeSearch the codebase for the POST handler for /customnode/install. Look for code that processes the 'pip' parameter in the request body.Affected if The code directly passes the pip field to pip install without allowlist validation
-
Check for pip field validation logicLocate any validation applied to the pip field. Search for allowlists, whitelist patterns, or input sanitization routines associated with this endpoint.Affected if No allowlist or validation routine exists for the pip field, or the validation can be bypassed
-
Verify if pip installation feature is enabledCheck the configuration file or feature flag that controls whether custom node pip installation is permitted. Look for settings like 'enable_custom_pip' or similar.Affected if The pip installation feature is enabled in configuration
-
Inspect request handling for arbitrary inputExamine how the pip field value is constructed into the pip install command. Look for string concatenation or formatting that accepts raw user input.Affected if The pip field value is used directly in a subprocess call without sanitization
Your environment is affected if the /customnode/install endpoint exists and accepts arbitrary pip package names without allowlist validation.

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 allowlist validation for the pip field, rejecting any input not matching pre-approved packages. Alternatively, disable direct pip installation and use a sandboxed environment for custom node installation.
