This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 3.8%, top 11% 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).

WebdriverIO is a test automation framework for unit, e2e and component testing using WebDriver, WebDriver BiDi and Appium. 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.
