CVE-2017-1000093: Jenkins Poll Scm

High severity, CVSS 8.8. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Jenkins Poll Scm: up to and including 1.3.1
