CVE-2017-1000093: Cross-Site Request Forgery (CSRF)

October 5, 2017 (updated October 17, 2017)

The Poll SCM Plugin was not requiring requests to its API be sent via POST, thereby opening itself to Cross-Site Request Forgery attacks. This allowed attackers to initiate polling of projects with a known name. While Jenkins in general does not consider polling to be a protection-worthy action as it’s similar to cache invalidation, the plugin specifically adds a permission to be able to use this functionality, and this issue undermines that permission.
