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 scripting (XSS) vulnerability in Jenkins before 1.640 and LTS before 1.625.2 allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors related to workspaces and archived artifacts.

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.

Jenkins before 1.638 and LTS before 1.625.2 do not properly verify the shared secret used in JNLP slave connections, which allows remote attackers to connect as slaves and obtain sensitive information or possibly gain administrative access by leveraging knowledge of the name of a slave.

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/.

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 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.

Jenkins before 1.587 and LTS before 1.580.1 do not properly ensure trust separation between a master and slaves, which might allow remote attackers to execute arbitrary code on the master by leveraging access to the slave.

The Fingerprints pages in Jenkins before 1.638 and LTS before 1.625.2 might allow remote attackers to obtain sensitive job and build name information via a direct request.

Jenkins before 1.638 and LTS before 1.625.2 allow remote attackers to obtain sensitive information via a direct request to queue/api.
