CVE-2024-32463 Information

Description

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.
