Apache Geode versions up to 1.12.2 and 1.13.2 are vulnerable to a deserialization of untrusted data flaw when using JMX over RMI on Java 11. Any user wishing to protect against deserialization attacks involving JMX or RMI should upgrade to Apache Geode 1.15. Use of 1.15 on Java 11 will automatically protect JMX over RMI against deserialization attacks. This should have no impact on performance since it only affects JMX/RMI which Gfsh uses to communicate with the JMX Manager which is hosted on a Locator.

Apache Geode versions up to 1.12.4 and 1.13.4 are vulnerable to a log file redaction of sensitive information flaw when using values that begin with characters other than letters or numbers for passwords and security properties with the prefix "sysprop-", "javax.net.ssl", or "security-". This issue is fixed by overhauling the log file redaction in Apache Geode versions 1.12.5, 1.13.5, and 1.14.0.
