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.

Jenkins before 1.583 and LTS before 1.565.3 allows remote attackers to cause a denial of service (thread consumption) via vectors related to a CLI handshake.

In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests.

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier was vulnerable to a UDP amplification reflection denial of service attack on port 33848.

Jenkins 2.333 and earlier, LTS 2.319.2 and earlier defines custom XStream converters that have not been updated to apply the protections for the vulnerability CVE-2021-43859 and allow unconstrained resource usage.

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.

An XML external entities (XXE) vulnerability in Jenkins Token Macro Plugin 2.7 and earlier allowed attackers able to control a the content of the input file for the "XML" macro to have Jenkins resolve external entities, resulting in the extraction of secrets from the Jenkins agent, server-side request forgery, or denial-of-service attacks.

The Pipeline: Input Step Plugin by default allowed users with Item/Read access to a pipeline to interact with the step to provide input. This has been changed, and now requires users to have the Item/Build permission instead.

Jenkins Oracle Cloud Infrastructure Compute Plugin 1.0.16 and earlier does not validate SSH host keys when connecting OCI clouds, enabling man-in-the-middle attacks.

Jenkins versions 2.88 and earlier and 2.73.2 and earlier stores metadata related to 'people', which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping, potentially resulting in problems like overwriting of unrelated configuration files.

The Jenkins 2.73.1 and earlier, 2.83 and earlier default form control for passwords and other secrets, <f:password/>, supports form validation (e.g. for API keys). The form validation AJAX requests were sent via GET, which could result in secrets being logged to a HTTP access log in non-default configurations of Jenkins, and made available to users with access to these log files. Form validation for <f:password/> is now always sent via POST, which is typically not logged.

Jenkins Swarm Plugin Client 3.4 and earlier bundled a version of the commons-httpclient library with the vulnerability CVE-2012-6153 that incorrectly verified SSL certificates, making it susceptible to man-in-the-middle attacks.

Jenkins Maven Plugin 2.17 and earlier bundled a version of the commons-httpclient library with the vulnerability CVE-2012-6153 that incorrectly verified SSL certificates, making it susceptible to man-in-the-middle attacks. Maven Plugin 3.0 no longer has a dependency on commons-httpclient.

Sandbox protection in Jenkins Pipeline: Groovy Plugin 2.78 and earlier can be circumvented through default parameter expressions in CPS-transformed methods.

Sandbox protection in Jenkins Script Security Plugin 1.69 and earlier could be circumvented during the script compilation phase by applying AST transforming annotations to imports or by using them inside of other annotations.

programs/pluto/ikev1.c in libreswan before 3.17 retransmits in initial-responder states, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed UDP packet. NOTE: the original behavior complies with the IKEv1 protocol, but has a required security update from the libreswan vendor; as of 2016-06-10, it is expected that several other IKEv1 implementations will have vendor-required security updates, with separate CVE IDs assigned to each.
