GHSA-pgpj-83g3-mfr2 Jenkins Google Compute Engine Plugin has incorrect permission checks

• Maven org.jenkins-ci.plugins:google-compute-engine: < 4.3.17.1 → fixed in 4.3.17.1 • Maven org.jenkins-ci.plugins:google-compute-engine: >= 4.5, < 4.551.v5a → fixed in 4.551.v5a

Jenkins Google Compute Engine Plugin 4.550.vb_327fca_3db_11 and earlier does not correctly perform permission checks in multiple HTTP endpoints. This allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to do the following: • Enumerate system-scoped credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability. • Connect to Google Cloud Platform using attacker-specified credentials IDs obtained through another method, to obtain information about existing projects. Google Compute Engine Plugin 4.551.v5a_4dc98f6962 requires Overall/Administer permission for the affected HTTP endpoints.
