Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
hibernate-validator versions before 6.2.0.Final are affected. The SafeHtmlValidator's isValid method can be bypassed by omitting the closing less-than character of a tag, so browsers may render the resulting invalid HTML, allowing HTML injection or cross-site scripting. Upgrade to 6.2.0.Final or later.
