A code execution vulnerability exists in the Stapler web framework used by Jenkins 2.153 and earlier, LTS 2.138.3 and earlier in stapler/core/src/main/java/org/kohsuke/stapler/MetaClass.java that allows attackers to invoke some methods on Java objects by accessing crafted URLs that were not intended to be invoked this way.
An information exposure vulnerability exists in Jenkins 2.153 and earlier, LTS 2.138.3 and earlier in DirectoryBrowserSupport.java that allows attackers with the ability to control build output to browse the file system on agents running builds beyond the duration of the build using the workspace browser.
A data modification vulnerability exists in Jenkins 2.153 and earlier, LTS 2.138.3 and earlier in User.java, IdStrategy.java that allows attackers to submit crafted user names that can cause an improper migration of user record storage formats, potentially preventing the victim from logging into Jenkins.
A denial of service vulnerability exists in Jenkins 2.153 and earlier, LTS 2.138.3 and earlier in CronTab.java that allows attackers with Overall/Read permission to have a request handling thread enter an infinite loop.
A sandbox bypass vulnerability exists in Script Security Plugin 1.47 and earlier in groovy-sandbox/src/main/java/org/kohsuke/groovy/sandbox/SandboxTransformer.java that allows attackers with Job/Configure permission to execute arbitrary code on the Jenkins master JVM, if plugins using the Groovy sandbox are installed.
A sandbox bypass vulnerability exists in Pipeline: Groovy Plugin 2.59 and earlier in groovy-sandbox/src/main/java/org/kohsuke/groovy/sandbox/SandboxTransformer.java, groovy-cps/lib/src/main/java/com/cloudbees/groovy/cps/SandboxCpsTransformer.java that allows attackers with Job/Configure permission, or unauthorized attackers with SCM commit privileges and corresponding pipelines based on Jenkinsfiles set up in Jenkins, to execute arbitrary code on the Jenkins master JVM
In all Kubernetes versions prior to v1.10.11, v1.11.5, and v1.12.3, incorrect handling of error responses to proxied upgrade requests in the kube-apiserver allowed specially crafted requests to establish a connection through the Kubernetes API server to backend servers, then send arbitrary requests over the same connection directly to the backend, authenticated with the Kubernetes API server's TLS credentials used to establish the backend connection.
psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because available stack space is not checked when the device remains the same.
psi/zicc.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a setcolorspace type confusion.
