+      <p>It was found that the fix to address CVE-2021-44228 in Apache
+       Log4j 2.15.0 was incomplete in certain non-default
+       configurations. This could allows attackers with control over
+       Thread Context Map (MDC) input data when the logging
+       configuration uses a non-default Pattern Layout with either a
+       Context Lookup (for example, $${ctx:loginId}) or a Thread
+       Context Map pattern (%X, %mdc, or %MDC) to craft malicious input
+       data using a JNDI Lookup pattern resulting in a denial of
+       service (DOS) attack. Log4j 2.15.0 makes a best-effort attempt
+       to restrict JNDI LDAP lookups to localhost by default. Log4j
+       2.16.0 fixes this issue by removing support for message lookup
+       patterns and disabling JNDI functionality by default.
