Summary

Jenkins GitHub Branch Source Plugin 1967.vdea_d580c1a_b_a_ and earlier lacks a permission check. Attackers with Overall/Read permission can connect to an attacker-specified URL using attacker-specified GitHub App credentials.

Risk Assessment

A low-privileged user can abuse the Jenkins server to connect to external resources and expose GitHub App credentials. This may lead to unauthorized access to repositories and GitHub integrations.

Recommendation

Update the Jenkins GitHub Branch Source Plugin to a version newer than 1967.vdea_d580c1a_b_a_ and restrict Overall/Read permission to trusted users.
