High (8.7) in coder code-marketplace. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in github.com/coder/code-marketplace 1.2.3-0.20260402184705-988440dee05f.
The Code Extension Marketplace is an open-source alternative to the VS Code Marketplace. Prior to 2.4.2, Zip Slip vulnerability in coder/code-marketplace allowed a malicious VSIX file to write arbitrary files outside the extension directory. ExtractZip passed raw zip entry names to a callback that wrote files via filepath.Join with no boundary check; filepath.Join resolved .. components but did not prevent the result from escaping the base path. This vulnerability is fixed in 2.4.2.
