Updated Patches released for v2.1.4 and v2.2.3
Though they are both extremely old versions, they were the release before a major version change and are/may still be in use. Please bear in mind we strongly recommend your installations be updated to a much newer version which contains many more fixes and new features. Having said that, these patches (v2.1.4patch9 and v2.2.3patch12) fix a security vulnerability reported by Balisong which might allow uploaded scripts to be executed.
