Jenkins incapptic connect uploader Plugin 1.15 and earlier stores tokens unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Extended Read permission, or access to the Jenkins controller file system.

Jenkins Dashboard View Plugin 2.18 and earlier does not perform URL validation for the Iframe Portlet's Iframe source URL, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure views.

Jenkins Extended Choice Parameter Plugin 346.vd87693c5a_86c and earlier does not escape the value and description of extended choice parameters of radio buttons or check boxes type, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.

Jenkins Semantic Versioning Plugin 1.13 and earlier does not restrict execution of an controller/agent message to agents, and implements no limitations about the file path that can be parsed, allowing attackers able to control agent processes to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

A cross-site request forgery (CSRF) vulnerability in Jenkins Kubernetes Continuous Deploy Plugin 2.3.1 and earlier allows attackers to connect to an attacker-specified SSH server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

** DISPUTED ** An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position is "this is not an authentication bypass, since nothing is being bypassed."

Missing Authorization in GitHub repository go-gitea/gitea prior to 1.16.4.

Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Authenticated users, with access to the configuration, can create SSH resource files in unintended directories, leading to the execution of arbitrary code. This issue has been resolved in versions 2.8.6, 2.9.6 and 2.10 of Icinga Web 2. Users unable to upgrade should limit access to the Icinga Web 2 configuration.

Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds.

An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session.
