Headlamp is an extensible Kubernetes web UI. A command injection vulnerability was discovered in the codeSign.js script used in the macOS packaging workflow of the Kubernetes Headlamp project. This issue arises due to the improper use of Node.js's execSync() function with unsanitized input derived from environment variables, which can be influenced by an attacker. The variables ${teamID}, ${entitlementsPath}, and ${config.app} are dynamically derived from the environment or application config and passed directly to the shell command without proper escaping or argument separation. This exposes the system to command injection if any of the values contain malicious input. This vulnerability is fixed in 0.31.1.
CVE-2025-53542
This high-severity CVE scores 7.7 under NVD CVSS v3. EPSS exploit probability: 0.7%, top 52% 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).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
