There is a cross-site scripting vulnerability in the way that Roller handles data supplied in the comments section of a web page running the Roller Weblogger software. This may allow an attacker to read or modify the data within the web browsers of users of sites running vulnerable versions of the Roller software.

An attacker may be able to obtain sensitive data from a user of a web site running a vulnerable version of Roller. Depending on the nature of the web site, this data may include passwords, credit card numbers, and any arbitrary information provided by the user. Likewise, information stored in cookies could be stolen or corrupted.

Upgrade
