Red Hat
Red Hat rates this Moderate.
Red Hat Product Security rates this vulnerability as Moderate because it enables a denial of service through resource exhaustion without compromising data integrity or confidentiality. Applications utilizing Hibernate Validator to process untrusted input may experience thread starvation or high CPU usage when validation message templates re-evaluate duplicate parameters via the expression language engine. Exploitation requires submitting tailored payloads to application endpoints performing Bean Validation, but it cannot be leveraged to achieve code execution or data leakage in typical deployments.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
