Description

Kaspersky GReAT experts examined ~130,000 pipelines on GitHub, and discovered more than ~250,000 potential issues.

Impact

Misconfigurations in GitHub Actions pipelines can potentially be exploited by attackers to compromise development environments or supply chains. Critical flaws found in some repositories could lead to supply chain compromise, enabling attackers to inject malicious code or steal secrets. While most issues are low or medium risk, the presence of high-risk and critical misconfigurations indicates a tangible threat to the security of CI/CD automation and associated infrastructure. This can result in unauthorized access, exposure of sensitive information, and compromise of software integrity.

Defensive guidance

Kaspersky has released a set of detection rules integrated into Kaspersky Container Security to identify misconfigurations in GitHub Actions. Developers and maintainers should review their CI/CD pipeline configurations, focusing on access permissions, dependency version pinning, secret management, and handling of external data. Addressing these misconfigurations proactively will reduce the risk of supply chain compromise. The critical issues identified have been reported to the respective repository maintainers for remediation.
