Secunia

Digital Security Research Group have reported some vulnerabilities in Claroline, which can be exploited by malicious people to conduct cross-site scripting or cross-site request forgery attacks.

1) Input passed to the "cwd" parameter in document/rqmkhtml.php (when "cmd" is set to "rqMkHtml") and in the URL to announcements/announcements.php, calendar/agenda.php, course/index.php, course_description/index.php, document/document.php, exercise/exercise.php, group/group_space.php, phpbb/newtopic.php, phpbb/reply.php, phpbb/viewtopic.php, wiki/wiki.php, and work/work.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. All scripts are located in the "claroline/" directory.

2) A vulnerability is caused due to the application allowing users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to change a user's password, by enticing a logged-in user to visit a malicious web site.

The vulnerabilities are reported in version 1.8.9. Prior versions may also be affected.

Solution
Update to version 1.8.10.
