Upgrade org.jenkins-ci.plugins:github-branch-source to version 1967.1969.v205fd594c821 or higher.
Overview
org.jenkins-ci.plugins:github-branch-source is a multibranch projects and organization folders from GitHub. Maintained by CloudBees, Inc.
Affected versions of this package are vulnerable to Missing Authorization in the GitHubAppCredentials descriptor through the testConnection handler. An attacker can trigger the GitHub App connection test by sending a POST request to descriptorByName/org.jenkinsci.plugins.github_branch_source.GitHubAppCredentials/testConnection, causing Jenkins to perform the test with attacker-supplied parameters without requiring Jenkins.MANAGE. This lets a low-privileged user invoke the credential validation path and force the controller to make outbound GitHub requests, resulting in unauthorized use of the test endpoint and potential exposure of connection behavior to users who should not be able to access it.
