Upstream source description

The 12 Step Meeting List WordPress plugin before 3.19.17 does not sanitise and escape a value submitted by unauthenticated users before storing it in its activity log and outputting it back in an admin area page, leading to a Stored Cross-Site Scripting issue which could be used against high privilege users such as admin.
