What is CVE-2017-1000093?
CVE-2017-1000093 is a high-severity vulnerability in n/a, published on 4 Oct 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-352
