Summary

A flaw exists in the 'isValid' method within the SafeHtmlValidator class of Hibernate Validator that allows for potential HTML injection and Cross-Site Scripting (XSS) attacks. This vulnerability occurs due to the improper handling of HTML tags, specifically when tag endings are omitted in a less-than character format. Consequently, browsers may render invalid HTML, which could be exploited by attackers to inject malicious scripts, compromising the security of affected applications.
