CRITICAL 9.8

DescriptionGitHub Advisory

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.

AnalysisAI

Code inclusion from untrusted source in Slyde presentation tool 0.0.4 and below. Automatically imports plugin files. Patch available.

Technical ContextAI

CWE-829 auto-importing plugin files.

RemediationAI

Update Slyde.
