Katalon Plugin 1.0.33 no longer stores the API keys directly, instead accessing them through its Credentials Plugin integration, once affected job configurations are saved again.

Jenkins Katalon Plugin 1.0.32 and earlier does not perform permission checks in several HTTP endpoints, allowing attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
