[org.jenkins-ci.plugins:config-file-provider] CSRF vulnerability in Jenkins Config File Provider Plugin allows deleting configuration files

Config File Provider Plugin 3.7.0 and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability.

This vulnerability allows attackers to delete configuration files corresponding to an attacker-specified ID.

This is due to an incomplete fix of SECURITY-938.

Config File Provider Plugin 3.7.1 requires POST requests for the affected HTTP endpoint.
