Description
SOGo before 5.12.13 contains a Sieve script injection vulnerability that allows authenticated users to inject arbitrary Sieve directives by inserting unescaped notification address values into a generated Sieve script. Attackers can embed Sieve redirect or discard statements within the notificationAddress preference to bypass the administrator-configured forwarding-domain constraint and redirect or discard incoming mail.
