CyberRota Analysis
AI-GeneratedThe vulnerability in the HTML5 scrubber of the affected Java products allows remote attackers to exploit a URL redirection flaw, enabling them to redirect users to untrusted sites via a <meta http-equiv="refresh"> element in sanitized HTML. Although this does not lead to script execution, it poses a risk of phishing and social engineering attacks. Organizations using html_sanitize_ex versions from 0.3.1 to 1.5.3 should prioritize patching to mitigate potential exploitation.

Original NVD Description
URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the HTML5 scrubber in rrrene html_sanitize_ex allows a remote attacker to force visitors of a page to navigate to a site of the attacker's choosing via a <meta http-equiv="refresh"> element in sanitized HTML. HtmlSanitizeEx.html5/1 keeps attacker-supplied <meta> elements in its output. A meta element acts on the whole document rather than on the fragment it was embedded in, so it can also declare document-wide directives such as Content-Security-Policy. This is not cross-site scripting. Browsers do not navigate a meta refresh to a javascript: URL, so the uppercase JAVASCRIPT: filter bypass yields no script execution and none was demonstrated. This issue affects html_sanitize_ex: from 0.3.1 before 1.5.3.
