Jenkins before versions 2.44, 2.32.2 is vulnerable to an information exposure in the internal API that allows access to item names that should not be visible (SECURITY-380). This only affects anonymous users (other users legitimately have access) that were able to get a list of items via an UnprotectedRootAction.

Jenkins before versions 2.44, 2.32.2 is vulnerable to a user data leak in disconnected agents' config.xml API. This could leak sensitive data such as API tokens (SECURITY-362).

jenkins-email-ext before version 2.57.1 is vulnerable to an Information Exposure. The Email Extension Plugins is able to send emails to a dynamically created list of users based on the changelogs, like authors of SCM changes since the last successful build. This could in some cases result in emails being sent to people who have no user account in Jenkins, and in rare cases even people who were not involved in whatever project was being built, due to some mapping based on the local-part of email addresses.

jenkins-mailer-plugin before version 1.20 is vulnerable to an information disclosure while using the feature to send emails to a dynamically created list of users based on the changelogs. This could in some cases result in emails being sent to people who have no user account in Jenkins, and in rare cases even people who were not involved in whatever project was being built, due to some mapping based on the local-part of email addresses.

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).

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier exposed session identifiers on a user's detail object in the whoAmI diagnostic page.

Jenkins 2.73.1 and earlier, 2.83 and earlier provides information about Jenkins user accounts which is generally available to anyone with Overall/Read permissions via the /user/(username)/api remote API. This included e.g. Jenkins users' email addresses if the Mailer Plugin is installed. The remote API now no longer includes information beyond the most basic (user ID and name) unless the user requesting it is a Jenkins administrator.

The remote API in Jenkins 2.73.1 and earlier, 2.83 and earlier at /computer/(agent-name)/api showed information about tasks (typically builds) currently running on that agent. This included information about tasks that the current user otherwise has no access to, e.g. due to lack of Item/Read permission. This has been fixed, and the API now only shows information about accessible tasks.

Docker Commons Plugin provides a list of applicable credential IDs to allow users configuring a job to select the one they'd like to use to authenticate with a Docker Registry. This functionality did not check permissions, allowing any user with Overall/Read permission to get a list of valid credentials IDs. Those could be used as part of an attack to capture the credentials using another vulnerability.

The re-key admin monitor was introduced in Jenkins 1.498 and re-encrypted all secrets in JENKINS_HOME with a new key. It also created a backup directory with all old secrets, and the key used to encrypt them. These backups were world-readable and not removed afterwards. Jenkins now deletes the backup directory, if present. Upgrading from before 1.498 will no longer create a backup directory. Administrators relying on file access permissions in their manually created backups are advised to check them for the directory $JENKINS_HOME/jenkins.security.RekeySecretAdminMonitor/backups, and delete it if present.

Jenkins Git Client Plugin 2.4.2 and earlier creates temporary file with insecure permissions resulting in information disclosure

The Jenkins 2.73.1 and earlier, 2.83 and earlier remote API at /queue/item/(ID)/api showed information about tasks in the queue (typically builds waiting to start). This included information about tasks that the current user otherwise has no access to, e.g. due to lack of Item/Read permission. This has been fixed, and the API endpoint is now only available for tasks that the current user has access to.

GitHub Branch Source provides a list of applicable credential IDs to allow users configuring a job to select the one they'd like to use. This functionality did not check permissions, allowing any user with Overall/Read permission to get a list of valid credentials IDs. Those could be used as part of an attack to capture the credentials using another vulnerability.

The Deploy to container Plugin stored passwords unencrypted as part of its configuration. This allowed users with Jenkins master local file system access, or users with Extended Read access to the jobs it is used in, to retrieve those passwords. The Deploy to container Plugin now integrates with Credentials Plugin to store passwords securely, and automatically migrates existing passwords.

Jenkins before 2.3 and LTS before 1.651.2 allow remote authenticated users with extended read access to obtain sensitive password information by reading a job configuration.

The API URL computer/(master)/api/xml in Jenkins before 2.3 and LTS before 1.651.2 allows remote authenticated users with extended read permission for the master node to obtain sensitive information about the global configuration via unspecified vectors.

The sidepanel widgets in the CLI command overview and help pages in Jenkins before 1.638 and LTS before 1.625.2 allow remote attackers to obtain sensitive information via a direct request to the pages.

Jenkins before 1.638 and LTS before 1.625.2 do not properly verify the shared secret used in JNLP slave connections, which allows remote attackers to connect as slaves and obtain sensitive information or possibly gain administrative access by leveraging knowledge of the name of a slave.

The Fingerprints pages in Jenkins before 1.638 and LTS before 1.625.2 might allow remote attackers to obtain sensitive job and build name information via a direct request.
