phlex is an open source framework for building object-oriented views in Ruby. There is a potential cross-site scripting (XSS) vulnerability that can be exploited via maliciously crafted user data. The filter to detect and prevent the use of the javascript: URL scheme in the href attribute of an <a> tag could be bypassed with tab \t or newline \n characters between the characters of the protocol, e.g. java\tscript:. This vulnerability is fixed in 1.10.1, 1.9.2, 1.8.3, 1.7.2, 1.6.3, 1.5.3, and 1.4.2. Configuring a Content Security Policy that does not allow unsafe-inline would effectively prevent this vulnerability from being exploited.
