DESCRIPTION:
A security issue and three vulnerabilities have been reported in
MyBB, where two have an unknown impact and others can be exploited by
malicious users to bypass certain security restrictions and by
malicious people to conduct cross-site scripting attacks.

1) The application does not properly verify permissions when
accessing forums with the "View only own threads" flag. This can be
exploited to e.g. disclose content of otherwise inaccessible forum
threads.

2) Certain input related to the debug page 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 the
context of an affected site.

3) Certain unspecified input is not properly sanitised in modcp.php
before being used. No further information is currently available.

4) Certain unspecified input is not properly sanitised in
calendar.php before being used. No further information is currently
available.

The security issue and vulnerabilities are reported in versions prior
to 1.6.10.

SOLUTION:
Update to version 1.6.10.

PROVIDED AND/OR DISCOVERED BY:
