Some vulnerabilities have been reported in Bandersnatch, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "date" and "limit" parameters in index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

NOTE: Potentially more parameters are affected.

2) Resource names saved from Jabber conversations are not properly sanitised before being stored. This can be exploited to insert arbitrary HTML and script code in a user's browser session in context of an affected site when the malicious conversation log is viewed.

NOTE: Potentially more Jabber conversation elements are affected.

3) Input passed to the "func", "date", and "jid" parameters in index.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.

The vulnerabilities are reported in version 0.4. Other versions may also be affected.
