What is CVE-2024-32463?

The Phlex framework, designed for crafting object-oriented views in Ruby, contains a vulnerability that allows for potential cross-site scripting (XSS) through improperly filtered user data. Specifically, attackers can circumvent protections against the javascript: URL scheme in <a> tags by introducing tab or newline characters within the protocol, leading to potential exploitation. To mitigate this risk, it is recommended for developers to implement a Content Security Policy (CSP) that prohibits the use of unsafe-inline, thereby enhancing defense against malicious injections.
