Name of the Vulnerable Software and Affected Versions MantisBT LinkedCustomFields plugin versions prior to 2.0.1

Description The issue allows cross-site scripting in the MantisBT LinkedCustomFields plugin, enabling Javascript execution when a crafted Custom Field is linked via the plugin and displayed when reporting a new Issue or editing an existing one. This can be mitigated by utilizing MantisBT's default Content Security Policy, which blocks script execution.
