XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.

A flaw was found in Jenkins. The Pipeline: Groovy Plugin uses the same checkout directories for distinct SCMs when reading the script file (typically Jenkinsfile) for Pipelines. This flaw allows attackers with item/configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents.

A flaw was found in Jenkins. The JenkinsPipeline: Shared Groovy Libraries uses the same checkout directories for distinct SCMs for Pipeline libraries. This flaw allows attackers with item/configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents. This allows attackers to compromise confidentiality, integrity, and availability.

A flaw was found in Jenkins. The Pipeline: Multibranch uses the same checkout directories for distinct SCMs for the readTrusted step. This flaw allows attackers with item/configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents.This allows attackers to compromise confidentiality, integrity, and availability.

A flaw was found in Jenkins. The Pipeline: Groovy Plugin follows symbolic links to locations outside of the checkout directory for the configured SCM when reading the script file (typically Jenkinsfile) for Pipelines. This flaw allows attackers who can configure Pipelines to read arbitrary files on the Jenkins controller file system.

A flaw was found in Jenkins. The Pipeline: Shared Groovy Libraries follows symbolic links to locations outside of the expected Pipeline library when reading files using the libraryResource step. This flaw allows attackers who can configure Pipelines to read arbitrary files on the Jenkins controller file system.

A flaw was found in Jenkins. The Pipeline: Shared Groovy Libraries does not restrict the names of resources passed to the libraryResource step. This flaw allows attackers who can configure Pipelines to read arbitrary files on the Jenkins controller file system.

A flaw was found in Jenkins. The Pipeline: Multibranch follows symbolic links to locations outside of the checkout directory for the configured SCM when reading files using the readTrusted step. This flaw allows attackers that can configure Pipelines, to read arbitrary files on the Jenkins controller file system.

A flaw was found in Jenkins. The Pipeline: Groovy Plugin includes password parameters from the original build in replayed builds. This flaw allows attackers with run/replay permission to obtain the values of password parameters passed to previous builds of a Pipeline.

A flaw was found in Jenkins. The Pipeline: Shared Groovy Libraries Plugin uses the same workspace directory for all checkouts of Pipeline libraries with the same name, regardless of the SCM used and the source of the library configuration. This flaw allows attackers with item/configure permission to execute arbitrary code in the context of the Jenkins controller, JVM, through crafted SCM contents if a global Pipeline library already exists.

A flaw was found in Jenkins. The Pipeline: Shared Groovy Libraries Plugin uses the names of Pipeline libraries to create directories without canonicalization or sanitization. This flaw allows attackers with item/configure permission to execute arbitrary code in the context of the Jenkins controller, JVM, using specially crafted library names if a global Pipeline library is already configured.

A flaw was found in Jenkins. The Pipeline: Shared Groovy Libraries plugin uses the names of Pipeline libraries to create cache directories without any sanitization. This flaw allows attackers with item/configure permission to execute arbitrary code in the context of the Jenkins controller JVM, using specially crafted library names if a global Pipeline library configured to use caching already exists.

A flaw was found in Jenkins pipeline-build-step where it revealed password parameter default values when generating a pipeline script using the Pipeline snippet generator. This flaw allows attackers with item/read permission to retrieve the default password parameter value from jobs and compromises confidentiality.
