Jenkins before 2.3 and LTS before 1.651.2 allows remote authenticated users to trigger updating of update site metadata by leveraging a missing permissions check. NOTE: this issue can be combined with DNS cache poisoning to cause a denial of service (service disruption).

Jenkins before 2.3 and LTS before 1.651.2 allow remote authenticated users with extended read access to obtain sensitive password information by reading a job configuration.

Jenkins before 2.3 and LTS before 1.651.2 allow remote authenticated users with read access to obtain sensitive plugin installation information by leveraging missing permissions checks in unspecified XML/JSON API endpoints.

Jenkins before 2.3 and LTS before 1.651.2 allow remote authenticated users with multiple accounts to cause a denial of service (unable to login) by editing the "full name."

Jenkins before 2.3 and LTS before 1.651.2 might allow remote authenticated users to inject arbitrary build parameters into the build environment via environment variables.

Multiple unspecified API endpoints in Jenkins before 1.650 and LTS before 1.642.2 allow remote authenticated users to execute arbitrary code via serialized data in an XML file, related to XStream and groovy.util.Expando.

Jenkins before 1.650 and LTS before 1.642.2 do not use a constant-time algorithm to verify CSRF tokens, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force approach.

Jenkins before 1.650 and LTS before 1.642.2 do not use a constant-time algorithm to verify API tokens, which makes it easier for remote attackers to determine API tokens via a brute-force approach.

CRLF injection vulnerability in the CLI command documentation in Jenkins before 1.650 and LTS before 1.642.2 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

The remoting module in Jenkins before 1.650 and LTS before 1.642.2 allows remote attackers to execute arbitrary code by opening a JRMP listener.

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.

Jenkins before 1.640 and LTS before 1.625.2 allow remote attackers to bypass the CSRF protection mechanism via unspecified vectors.

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.

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.

The Jenkins CLI subsystem in Jenkins before 1.638 and LTS before 1.625.2 allows remote attackers to execute arbitrary code via a crafted serialized Java object, related to a problematic webapps/ROOT/WEB-INF/lib/commons-collections-*.jar file and the "Groovy variant in 'ysoserial'".

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 allow remote attackers to obtain sensitive information via a direct request to queue/api.

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/.
