Some vulnerabilities have been reported in TikiWiki, where some have unknown impacts and others can be exploited by malicious people to conduct cross-site scripting attacks.

1) Input passed into the "movie" parameter in tiki-listmovies.php is not properly sanitised before being used, which can be exploited to disclose the first 1000 bytes of arbitrary files via directory traversal attacks.

2) Input passed to the "area_name" parameter in tiki-special_chars.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.

3) Certain unspecified vulnerabilities exist in tiki-edit_css.php, tiki-list_games.php, and tiki-g-admin_shared_source.php. More information is currently not available.
