CVE-2025-51387 is a critical vulnerability affecting GitKraken Desktop versions 10.8.0 and 11.1.0, stemming from misconfigurations in the Electron framework's Fuse settings. Electron Fuses are security mechanisms designed to restrict the capabilities of Electron applications, preventing them from executing potentially dangerous operations. In this case, the vulnerability arises because the 'RunAsNode' fuse is enabled, allowing the application to run in Node.js mode, and the 'EnableNodeCliInspectArguments' fuse is not disabled, which permits passing Node.js CLI inspection arguments. This combination enables an attacker to execute arbitrary code within the context of the GitKraken Desktop application by injecting malicious arguments that the application processes as Node.js commands. Since GitKraken is a widely used Git client for developers, this vulnerability could be exploited to execute malicious code on the victim's machine, potentially leading to unauthorized access, data theft, or further compromise of the development environment. The vulnerability does not require user interaction beyond launching the application with crafted arguments, and no authentication is needed to exploit it if the attacker can influence the application's startup parameters. No known exploits are currently reported in the wild, and no official patches or mitigations have been published at the time of this analysis.

For European organizations, the impact of CVE-2025-51387 could be significant, especially for software development teams relying on GitKraken Desktop as their Git client. Exploitation could lead to arbitrary code execution on developers' workstations, compromising source code integrity, leaking sensitive intellectual property, or enabling lateral movement within corporate networks. This could result in intellectual property theft, disruption of development workflows, and potential introduction of malicious code into software supply chains. Given the critical role of software development in many European industries, including finance, automotive, and telecommunications, this vulnerability poses a substantial risk to confidentiality, integrity, and availability of critical assets. Furthermore, compromised developer machines could be leveraged as entry points for broader attacks against organizational infrastructure.

To mitigate this vulnerability, European organizations should: 1) Immediately audit their use of GitKraken Desktop to identify installations of versions 10.8.0 and 11.1.0. 2) Restrict execution of GitKraken Desktop to trusted users and environments, preventing untrusted users from launching the application with arbitrary arguments. 3) Employ application whitelisting and endpoint protection solutions to monitor and block suspicious command-line arguments or process behaviors associated with Node.js execution modes. 4) Until official patches are released, consider temporarily replacing GitKraken Desktop with alternative Git clients that do not exhibit this vulnerability. 5) Educate developers and IT staff about the risk of launching GitKraken with untrusted parameters and enforce strict controls on software execution policies. 6) Monitor network and endpoint logs for unusual activity indicative of exploitation attempts, such as unexpected Node.js processes spawned by GitKraken. 7) Engage with GitKraken vendor support channels to obtain updates and patches as soon as they become available and apply them promptly.
