CVE-2025-1568 is a high-severity access control vulnerability affecting Google ChromeOS version 16063.87.0. The flaw resides in the Gerrit chromiumos project configuration, specifically in the handling of project.config files within Gerrit, a web-based code review tool used by the ChromeOS development infrastructure. An attacker with a registered Gerrit account can exploit insufficient access controls and misconfigurations to inject malicious code into ChromeOS projects. This injection occurs via editing trusted pipelines, which are automated workflows that build, test, and deploy ChromeOS components. Because these pipelines are trusted, malicious modifications can lead to remote code execution (RCE) on systems running ChromeOS, as well as denial of service (DoS) conditions. The vulnerability is classified under CWE-284 (Improper Access Control), indicating that the system fails to properly restrict access to critical functions. The CVSS v3.1 base score is 8.8, reflecting a high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and requiring privileges (a registered Gerrit account) but no user interaction. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in February 2025 and published in April 2025, indicating recent discovery and disclosure. The technical risk stems from the ability of an attacker to leverage trusted build and deployment pipelines to insert malicious code that could propagate into official ChromeOS releases or updates, potentially compromising end-user devices or infrastructure relying on ChromeOS.

For European organizations, the impact of CVE-2025-1568 could be significant, especially for those relying on ChromeOS devices in enterprise environments, educational institutions, or public sector deployments. Successful exploitation could lead to unauthorized remote code execution on ChromeOS devices, allowing attackers to gain control over affected systems, exfiltrate sensitive data, or disrupt operations via denial of service. Since ChromeOS is often used in cloud-centric and managed device scenarios, a compromised build pipeline could undermine the trustworthiness of software updates, leading to widespread compromise. This risk is particularly acute for organizations with large ChromeOS deployments or those involved in software development or integration with ChromeOS components. Additionally, the attack vector requires a registered Gerrit account, which implies that insider threats or compromised developer credentials could be leveraged, raising concerns about supply chain security. The vulnerability could also affect organizations that develop or maintain ChromeOS-based solutions or contribute to the ChromiumOS project, potentially impacting the broader ecosystem. The lack of known exploits in the wild provides a window for mitigation, but the high severity score and potential for remote code execution necessitate urgent attention.

To mitigate CVE-2025-1568, organizations should take the following specific actions: 1) Immediately audit and restrict access to Gerrit accounts, ensuring that only trusted and necessary personnel have permissions to edit project configurations and pipelines. Implement strict role-based access controls (RBAC) and enforce the principle of least privilege. 2) Review and harden Gerrit project.config files and pipeline configurations to eliminate misconfigurations that allow unauthorized edits. Employ configuration management tools to enforce consistency and detect unauthorized changes. 3) Monitor Gerrit activity logs for unusual or unauthorized modifications to project configurations and pipeline definitions, enabling rapid detection of suspicious behavior. 4) Coordinate with Google and ChromeOS maintainers for timely patches or updates addressing this vulnerability; apply patches as soon as they become available. 5) Implement multi-factor authentication (MFA) for Gerrit accounts to reduce the risk of credential compromise. 6) For organizations deploying ChromeOS devices, consider additional endpoint monitoring and anomaly detection to identify potential exploitation attempts. 7) Educate developers and administrators about the risks of supply chain attacks and the importance of securing development infrastructure. These measures go beyond generic advice by focusing on securing the specific attack surface related to Gerrit project configuration and pipeline management.
