Description:
Two vulnerabilities have been reported in HTML Purifier, which can be exploited by malicious people to conduct cross-site scripting or script insertion attacks.
Input passed to the library containing CSS data is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is viewed.
Successful exploitation of one of the vulnerabilities requires that the output encoding is set to Shift_JIS.
The vulnerabilities are reported in all versions prior to 2.1.5 and 3.1.1.
