How to Fix CVE-2026-26974

To remediate this vulnerability, upgrade all affected @tygo van den hurk/slyde dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@tygo-van-den-hurk/slyde fixed: 0.0.5 
npm install @tygo-van-den-hurk/slyde@0.0.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @tygo-van-den-hurk/slyde

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-26974, inspect your project dependencies using npm:

npm ls @tygo-van-den-hurk/slyde

Analyze the terminal output to locate any version of @tygo van den hurk/slyde in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.5), your application is affected.

Note: The npm ls @tygo-van-den-hurk/slyde command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-829: Inclusion of Functionality from Untrusted Control Sphere, where the product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere. In @tygo van den hurk/slyde, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact This is a **remote code execution (RCE) vulnerability**. Node.js automatically imports `**/*.plugin.{js,mjs}` files including those from `node_modules`, so any malicious package with a `.plugin.js` file could execute arbitrary code when installed or required. **All projects using this loading behavior are affected**, especially those installing untrusted packages. ### Patches The issue has been **patched in v0.0.5**. Users should upgrade to **v0.0.5 or later** to mitigate the vulnerability. ### Workarounds - Audit and restrict which packages are installed in `node_modules`. ### References - [CWE-94: Improper Control of Generation of Code](https://cwe.mitre.org/data/definitions/94.html) - GitHub Security Advisories documentation: [https://docs.github.com/en/code-security/security-advisories](https://docs.github.com/en/code-security/security-advisories)
