CVE-2016-6497
main/java/org/apache/directory/groovyldap/LDAP.java in the Groovy LDAP API in Apache allows attackers to conduct LDAP entry poisoning attacks by leveraging setting returnObjFlag to true for all search methods.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
