CVE-2025-58460 is a vulnerability identified in the Jenkins OpenTelemetry Plugin versions 3.1543.v8446b_92b_cd64 and earlier. The core issue is a missing permission check within the plugin, which allows attackers who have Overall/Read permission on the Jenkins instance to exploit the vulnerability. Specifically, these attackers can connect to an attacker-controlled URL using credentials IDs that they have obtained through other means. This flaw enables the attacker to capture credentials stored within Jenkins, potentially exposing sensitive authentication data. The vulnerability arises because the plugin does not properly verify whether the user has the necessary permissions to perform actions involving these credentials, thereby allowing unauthorized use of stored credentials. Since Jenkins is widely used for continuous integration and continuous deployment (CI/CD) pipelines, compromising stored credentials can lead to further attacks on connected systems and infrastructure. The vulnerability does not require elevated permissions beyond Overall/Read, which is a relatively low privilege level in Jenkins, increasing the risk of exploitation. There are no known exploits in the wild at the time of publication, and no CVSS score has been assigned yet. The absence of a patch link suggests that a fix may not have been released at the time of this report.

For European organizations, this vulnerability poses a significant risk, especially for those relying on Jenkins for their software development lifecycle. The ability to capture stored credentials can lead to unauthorized access to critical infrastructure, source code repositories, deployment environments, and other integrated services. This can result in data breaches, intellectual property theft, disruption of services, and potential lateral movement within corporate networks. Given the widespread adoption of Jenkins in Europe across industries such as finance, manufacturing, and technology, the impact could be broad. Organizations that have not restricted Overall/Read permissions or have not segmented their Jenkins environments may face increased exposure. Additionally, the compromise of credentials can facilitate supply chain attacks, which have been a growing concern in Europe. The lack of a known exploit in the wild provides a window for proactive mitigation, but the ease of exploitation due to low permission requirements elevates the threat level.

European organizations should immediately audit their Jenkins environments to identify users with Overall/Read permissions and assess whether these permissions are strictly necessary. Restricting Overall/Read permissions to trusted users only is critical. Administrators should monitor and review the usage of credentials IDs within Jenkins and implement strict access controls and logging to detect suspicious activities. Applying the latest updates and patches from the Jenkins project as soon as they become available is essential. If a patch is not yet released, consider temporarily disabling or restricting the use of the OpenTelemetry Plugin until a fix is deployed. Additionally, organizations should implement network-level controls to restrict Jenkins instances from making outbound connections to untrusted URLs, thereby limiting the attacker's ability to exfiltrate credentials. Employing credential vaulting solutions external to Jenkins and minimizing the storage of sensitive credentials within Jenkins can further reduce risk. Finally, enhancing monitoring and alerting for anomalous Jenkins activity will help detect exploitation attempts early.
