CVSS 3.1
7.1 highCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:NCVE-2024-32463
High (7.1). EPSS 0.6% chance of exploitation in the next 30 days. Fixed in phlex 1.10.1, 1.4.2, 1.5.3.
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.
