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.
