CVE-2021-21644
CSRF vulnerability in Jenkins Config File Provider Plugin allows deleting configuration files
Description
Jenkins 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](https://www.jenkins.io/security/advisory/2018-09-25/#SECURITY-938). Jenkins Config File Provider Plugin 3.7.1 requires POST requests for the affected HTTP endpoint.
