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.

A improper authorization vulnerability exists in Jenkins 2.137 and earlier, 2.121.2 and earlier in UpdateCenter.java that allows attackers to cancel a Jenkins restart scheduled through the update center.

A exposure of sensitive information vulnerability exists in Jenkins 2.137 and earlier, 2.121.2 and earlier in Computer.java that allows attackers With Overall/Read permission to access the connection log for any agent.

A improper authentication vulnerability exists in Jenkins 2.137 and earlier, 2.121.2 and earlier in SecurityRealm.java, TokenBasedRememberMeServices2.java that allows attackers with a valid cookie to remain logged in even if that feature is disabled.

A denial of service vulnerability exists in Jenkins 2.137 and earlier, 2.121.2 and earlier in CronTab.java that allows attackers with Overall/Read permission to have a request handling thread enter an infinite loop.

A denial of service vulnerability exists in Jenkins 2.137 and earlier, 2.121.2 and earlier in BasicAuthenticationFilter.java, BasicHeaderApiTokenAuthenticator.java that allows attackers to create ephemeral in-memory user records by attempting to log in using invalid credentials.

A vulnerability exists in Jenkins 2.137 and earlier, 2.121.2 and earlier in XStream2.java that allows attackers to have Jenkins resolve a domain name when deserializing an instance of java.net.URL.

A exposure of sensitive information vulnerability exists in Jenkins 2.132 and earlier, 2.121.1 and earlier in Plugin.java that allows attackers to determine the date and time when a plugin HPI/JPI file was last extracted, which typically is the date of the most recent installation/upgrade.

A server-side request forgery vulnerability exists in Jenkins 2.120 and older, LTS 2.107.2 and older in ZipExtractionInstaller.java that allows users with Overall/Read permission to have Jenkins submit a HTTP GET request to an arbitrary URL and learn whether the response is successful (200) or not.

A path traversal vulnerability exists in Jenkins 2.120 and older, LTS 2.107.2 and older in FilePath.java, SoloFilePathFilter.java that allows malicious agents to read and write arbitrary files on the Jenkins master, bypassing the agent-to-master security subsystem protection.

A improper neutralization of control sequences vulnerability exists in Jenkins 2.120 and older, LTS 2.107.2 and older in HudsonPrivateSecurityRealm.java that allows users to sign up using user names containing control characters that can then appear to have the same name as other users, and cannot be deleted via the UI.

A information exposure vulnerability exists in Jenkins 2.120 and older, LTS 2.107.2 and older in AboutJenkins.java, ListPluginsCommand.java that allows users with Overall/Read access to enumerate all installed plugins.

Jenkins before versions 2.44, 2.32.2 uses AES ECB block cipher mode without IV for encrypting secrets which makes Jenkins and the stored secrets vulnerable to unnecessary risks (SECURITY-304).

jenkins before versions 2.44, 2.32.2 is vulnerable to an information disclosure vulnerability in search suggestions (SECURITY-385). The autocomplete feature on the search box discloses the names of the views in its suggestions, including the ones for which the current user does not have access to.

jenkins before versions 2.44, 2.32.2 is vulnerable to a persisted cross-site scripting vulnerability in console notes (SECURITY-382). Jenkins allows plugins to annotate build logs, adding new content or changing the presentation of existing content while the build is running. Malicious Jenkins users, or users with SCM access, could configure jobs or modify build scripts such that they print serialized console notes that perform cross-site scripting attacks on Jenkins users viewing the build logs.

jenkins before versions 2.44, 2.32.2 is vulnerable to a user creation CSRF using GET by admins. While this user record was only retained until restart in most cases, administrators' web browsers could be manipulated to create a large number of user records (SECURITY-406).

jenkins before versions 2.44, 2.32.2 is vulnerable to a persisted cross-site scripting in search suggestions due to improperly escaping users with less-than and greater-than characters in their names (SECURITY-388).

jenkins before versions 2.44, 2.32.2 is vulnerable to an improper blacklisting of the Pipeline metadata files in the agent-to-master security subsystem. This could allow metadata files to be written to by malicious agents (SECURITY-358).

Jenkins before versions 2.44, 2.32.2 is vulnerable to a remote code execution vulnerability involving the deserialization of various types in javax.imageio in XStream-based APIs (SECURITY-383).

In jenkins before versions 2.44, 2.32.2 node monitor data could be viewed by low privilege users via the remote API. These included system configuration and runtime information of these nodes (SECURITY-343).
