User specific ticket permissions
This plugin allows administrators to add permissions at user-level. A user can be defined as a reporter, viewer or owner for any ticket and not be able to see any other ticket. This is useful in situations where developers and users are involved in some parts of the project, say milestones or phases, but not in others.
Warning: For versions of Trac prior to 1.0.2, if the plugin is removed, disabled, or fails to load, Trac will display private tickets to anyone with
TICKET_VIEW permission and the
TICKET_VIEW* permission restrictions will not have any effect. See #5784 and t:#10285 for more information.
If you have any issues, create a new ticket.

The plugin is also released on PyPi.
General instructions on installing Trac plugins can be found on the TracPlugins page.
