The Safemode gem before 1.2.4 for Ruby, when initialized with a delegate object that is a Rails controller, allows context-dependent attackers to obtain sensitive information via the inspect method.

rubygem-safemode, as used in Foreman, versions 1.3.2 and earlier are vulnerable to bypassing safe mode limitations via special Ruby syntax. This can lead to deletion of objects for which the user does not have delete permissions or possibly to privilege escalation.
