Some vulnerabilities and a weakness have been reported in Gallery, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose sensitive information, and manipulate data.

1) Input passed in the URL to unspecified scripts 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.

2) The vulnerability is caused due to improper access restriction in the album-select module. This can be exploited to disclose album titles when adding albums to a hidden album.

3) The vulnerability is caused due to improper access restriction when extracting ZIP archives. This can be exploited to create sub-albums without the right credentials.

4) The weakness is caused due to unspecified errors in embed.php. This can be exploited to disclose the full path to the application.

5) The vulnerability is caused due to improper access restriction in the Password module. This can be exploited to bypass view permissions for non-album items.

Successful exploitation of this vulnerability requires that the item is password protected.

The vulnerabilities are reported in all 2.x versions before 2.2.5.
