What is CVE-2025-53652?

CVE-2025-53652 is a vulnerability categorized as an input validation flaw found in the Jenkins Git Parameter Plugin, specifically versions up to and including 439.vb_0e46ca_14534. This plugin is integral to Jenkins, a popular open-source automation server used for building, testing, and deploying applications. The vulnerability arises from the plugin's failure to adequately validate the values submitted to Git parameters against predefined choices, presenting a significant risk for organizations using this software. If exploited, attackers with Item or Build permissions can inject arbitrary values into these parameters, which could potentially lead to the execution of malicious commands or scripts during the build process. This vulnerability compromises the integrity and security of automated workflows and poses a threat to the overall security and operational stability of affected systems.

Potential impact of CVE-2025-53652

Arbitrary Code Execution: The most significant risk associated with this vulnerability is the potential for attackers to execute arbitrary code within the Jenkins environment. By injecting harmful parameters, attackers can manipulate build processes to run malicious code, leading to unauthorized access and control over the server.
Compromise of Build Integrity: As Jenkins is often used in DevOps environments to automate software development processes, this vulnerability can undermine the integrity of the entire build pipeline. Injected parameters can lead to compromised application builds, where malicious code could be included in deployed software, affecting end-users and systems.
Data Breaches and Information Disclosure: Exploitation of this vulnerability can lead to exposure of sensitive data stored in the Jenkins environment. Attackers may gain access to credentials, configuration files, and other sensitive information, which can be leveraged for further attacks or sold on the dark web, resulting in severe repercussions for an organization’s data security and compliance standing.
