The Plugins Manager in Jenkins before 1.640 and LTS before 1.625.2 does not verify checksums for plugin files referenced in update site data, which makes it easier for man-in-the-middle attackers to execute arbitrary code via a crafted plugin.
Cross-site request forgery (CSRF) vulnerability in Jenkins before 1.640 and LTS before 1.625.2 allows remote attackers to hijack the authentication of administrators for requests that have unspecified impact via vectors related to the HTTP GET method.
Apache ActiveMQ 5.x before 5.13.0 does not restrict the classes that can be serialized in the broker, which allows remote attackers to execute arbitrary code via a crafted serialized Java Message Service (JMS) ObjectMessage object.
Cross-site scripting (XSS) vulnerability in the slave overview page in Jenkins before 1.638 and LTS before 1.625.2 allows remote authenticated users with certain permissions to inject arbitrary web script or HTML via the slave offline status message.
Jenkins before 1.638 and LTS before 1.625.2 allow attackers to bypass intended slave-to-master access restrictions by leveraging a JNLP slave. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-3665.
Jenkins before 1.638 and LTS before 1.625.2 do not properly restrict access to API tokens which might allow remote administrators to gain privileges and run scripts by using an API token of another user.
Directory traversal vulnerability in Jenkins before 1.638 and LTS before 1.625.2 allows remote attackers to list directory contents and read arbitrary files in the Jenkins servlet resources via directory traversal sequences in a request to jnlpJars/.
The sidepanel widgets in the CLI command overview and help pages in Jenkins before 1.638 and LTS before 1.625.2 allow remote attackers to obtain sensitive information via a direct request to the pages.
