The webhook endpoint in Jenkins Gogs Plugin 1.0.15 and earlier provides unauthenticated attackers information about the existence of jobs in its output.

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-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.

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).

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 Mercurial Plugin 1251.va_b_121f184902 and earlier provides information about which jobs were triggered or scheduled for polling through its webhook endpoint, including jobs the user has no permission to access.

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 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.

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.

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.

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.
