Cross-site scripting (XSS) vulnerability in the viewqueryform function in lib/viewvc.py in ViewVC before 1.0.10, and 1.1.x before 1.1.4, allows remote attackers to inject arbitrary web script or HTML via "user-provided input."

Cross-site scripting (XSS) vulnerability in ViewVC 1.1 before 1.1.5 and 1.0 before 1.0.11, when the regular expression search functionality is enabled, allows remote attackers to inject arbitrary web script or HTML via vectors related to "searchre input," a different vulnerability than CVE-2010-0736.

query.py in the query interface in ViewVC before 1.1.3 does not reject configurations that specify an unsupported authorizer for a root, which might allow remote attackers to bypass intended access restrictions via a query.

ViewVC before 1.1.3 composes the root listing view without using the authorizer for each root, which might allow remote attackers to discover private root names by reading this view.

The SVN revision view (lib/vclib/svn/svnrepos.py) in ViewVC before 1.1.15 does not properly handle log messages when a readable path is copied from an unreadable path, which allows remote attackers to obtain sensitive information, related to a "log msg leak."

The remote SVN views functionality (lib/vclib/svn/svnra.py) in ViewVC before 1.1.15 does not properly perform authorization, which allows remote attackers to bypass intended access restrictions via unspecified vectors.
