All affected installations are encouraged to upgrade as soon as
possible.

Vulnerability Details
=====================

Class:       Manipulation of Data
Versions:    2.17.4 and higher
Description: Quips, which are displayed at the top of bug lists, can be
             suggested by all users, but administrators can control
which ones to display. By using a well crafted URL, unprivileged
             users can bypass access checks and approve or disapprove
             quips themselves.
