Apache Geode versions up to 1.12.5, 1.13.4 and 1.14.0 are vulnerable to a deserialization of untrusted data flaw when using JMX over RMI on Java 8. Any user still on Java 8 who wishes to protect against deserialization attacks involving JMX or RMI should upgrade to Apache Geode 1.15 and Java 11. If upgrading to Java 11 is not possible, then upgrade to Apache Geode 1.15 and specify "--J=-Dgeode.enableGlobalSerialFilter=true" when starting any Locators or Servers. Follow the documentation for details on specifying any user classes that may be serialized/deserialized with the "serializable-object-filter" configuration option. Using a global serial filter will impact performance.
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.
