CVE-2026-39866 Apr 21, 01:19 HIGH This Week

Command injection in Lawnchair's GitHub Actions workflow allows authenticated repository contributors to execute arbitrary code on GitHub-hosted CI/CD runners. The vulnerability affects Lawnchair for Android versions prior to commit fcba413f5 and stems from unsanitized workflow_dispatch inputs in release_update.yml. Authenticated attackers with repository write access can inject shell commands through workflow parameters, achieving full code execution in the build environment. A patch is available (commit fcba413f5), and the CVSS vector indicates this is a network-accessible, low-complexity attack requiring low privileges. CVSS v4.0 score of 7.4 reflects high confidentiality, integrity, and availability impact scoped to the vulnerable CI/CD system. EPSS data not provided; no CISA KEV listing at time of analysis.
