CVE-2023-24434: CSRF vulnerability in Jenkins GitHub Pull Request Builder Plugin

The vulnerability stems from two flaws explicitly mentioned in SECURITY-2789 (2): 1) Missing permission checks in form validation methods, and 2) Lack of POST request requirements enabling CSRF. While exact function names aren't provided in the advisory, Jenkins plugin security patterns indicate that form validation methods for credential configuration (like test-connection endpoints for external services) would be the attack vector. These methods would typically be named doTest* or doValidate* in Java controllers handling plugin configuration.
