Description

Vvveb before 1.0.8.3 contains an uncontrolled recursion vulnerability in the admin controller dispatch cycle where Base::init() repeatedly invokes permission() on error handlers, causing infinite recursion until PHP memory limits are exhausted. Attackers can send sustained requests to forbidden admin URLs from a low-privilege account to exhaust PHP memory on all workers and cause denial of service to legitimate traffic.
