EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 57% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Slyde is a program that creates animated presentations from XML. In versions 0.0.4 and below, Node.js automatically imports **/*.plugin.{js,mjs} files including those from node_modules, so any malicious package with a .plugin.js file can execute arbitrary code when installed or required. All projects using this loading behavior are affected, especially those installing untrusted packages. This issue has been fixed in version 0.0.5. To workaround this issue, users can audit and restrict which packages are installed in node_modules.
