Description

Jenkins GitHub Branch Source Plugin versions 1967.vdea_d580c1a_b_a_ and earlier do not perform a permission check in a method implementing form validation.

This allows attackers with Overall/Read permission to connect to an attacker-specified URL with attacker-specified GitHub App credentials.

GitHub Branch Source Plugin 1967.1969.v205fd594c821 requires Overall/Manage permission to perform the connection test.
