Package Instance

Missing authorization in Jenkins Kubernetes Plugin
Jenkins Kubernetes Plugin prior to 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.

An enumeration of credentials IDs in Kubernetes Plugin 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 requires the appropriate permissions.

XXE vulnerability in Jenkins Mercurial Plugin
Jenkins Mercurial Plugin prior to 2.12, 2.10.1, 2.9.1, and 2.8.1 does not configure its XML changelog parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Mercurial Plugin 2.12, 2.10.1, 2.9.1, and 2.8.1 disables external entity resolution for its XML parser.

Exposure of Sensitive Information to an Unauthorized Actor in Jenkins Kubernetes Plugin
Jenkins Kubernetes Plugin prior to 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 includes a feature to replace placeholders in pod template and container template fields with environment variable values.

This feature allows low-privilege users to access possibly sensitive Jenkins controller environment variables.

Kubernetes Plugin 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 disables this feature.

Missing Authorization in Jenkins Kubernetes Plugin
Jenkins Kubernetes Plugin prior to 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to list global pod template names.

Kubernetes Plugin 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 requires Overall/Administer permission to list global pod template names.

Missing Authorization in Jenkins Mercurial Plugin
Mercurial Plugin prior to 2.12, 2.10.1, 2.9.1, and 2.8.1 does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to obtain a list of names of configured Mercurial installations.

Mercurial Plugin 2.12, 2.10.1, 2.9.1, and 2.8.1 performs permission checks when listing configured Mercurial installations.

XXE vulnerability in Jenkins Subversion Plugin
Jenkins Subversion Plugin 2.13.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Jenkins Subversion Plugin 2.13.2 disables external entity resolution for its XML parser.
