Cross-site scripting (XSS) vulnerability in the RSS feed reader functionality in Lunascape 4.1.3 build2 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Lunascape 5.1.3 and 5.1.4 allows remote attackers to spoof the address bar, via window.open with a relative URI, to show an arbitrary URL on the web site visited by the victim, as demonstrated by a visit to an attacker-controlled web page, which triggers a spoofed login form for the site containing that page. NOTE: a related attack was reported in which an arbitrary file: URL is shown.
