The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to the sandbox protection in the affected plugin can be circumvented through default parameter expressions in constructors. A remote authenticated attacker can specify and run sandboxed scripts to execute arbitrary code in the context of the Jenkins master JVM.


3) Stored cross-site scripting (CVE-ID: CVE-2019-10432)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to the affected plugin does not escape the project or build display name shown in the frame HTML page.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


4) Input validation error (CVE-ID: CVE-2019-11255)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied input in Kubernetes CSI sidecar containers for external-provisioner (versions prior to 0.4.3 and 1.0.2, in version 1.1,  and versions prior to 1.2.2 and 1.3.1), external-snapshotter (versions prior to 0.4.2 and 1.0.2, in version 1.1, versions prior to 1.2.2), and external-resizer (versions 0.1,  and 0.2) . A local user can gain unauthorized PersistentVolume data access or volume mutation during snapshot, restore from snapshot, cloning and resizing operations.
