Description:
SEC Consult has reported some vulnerabilities in Nag, which can be exploited by malicious users to conduct script insertion attacks.

Some input passed to certain tasklist names and task data fields isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed.

The vulnerabilities have been reported in version 2.0.3 and prior.

Solution:
Update to version 2.0.4.
