Description Timothy Walsh 2015-08-31 04:42:26 UTC

We have identified a small vulnerability in Hibernate Validator which is used in at least WildFly and JBoss EAP. 
https://issues.jboss.org/browse/WFLY-5223 [Open URL]
https://hibernate.atlassian.net/browse/HV-1012 [Open URL]
The vulnerability is in the dependency jsoup. Our understanding is that the likely vector OS that :
- an app developer guards a field as safe html via Hibernate Validator
- a malicious user sends a non safe html snippet not properly detected
- the application then uses the html believing it is safe.
