| Doc Text: |
A flaw was found in Hibernate Validator starting with version 5.4.1. This vulnerability allows an unauthenticated remote attacker to cause a Denial of Service (DoS) by submitting specially crafted input containing unescaped message parameters. Improper escaping allows user-supplied data to be re-evaluated during Expression Language (EL) processing, leading to excessive resource consumption and application unresponsiveness.
