Cross-site scripting (XSS) vulnerability in Horde Turba module before 1.2.5 allows remote attackers to inject arbitrary web script or HTML via the parent's frame page title.

Cross-site scripting (XSS) vulnerability in imp/test.php in Horde Turba Contact Manager H3 2.2.1 and other versions before 2.3.1, and possibly other Horde Project products, allows remote attackers to inject arbitrary web script or HTML via the User field in an IMAP session.

Cross-site scripting (XSS) vulnerability in services/obrowser/index.php in Horde 3.2 and Turba 2.2 allows remote attackers to inject arbitrary web script or HTML via the contact name.

It was reported that turba does not properly check permissions on address books, allowing users to modify addresses in other users' address books. This problem affects both shared and non-shared address books. Knowing (or guessing) the objectid seems to be sufficient to allow modification of other users' addresses.
