+============================================
+
+{% trans -%}
+I2P is not affected by the log4j 0-Day vulnerability which was published
+yesterday, CVE-2021-44228. I2P doesn't use log4j for logging, however we also
+needed to review our dependencies for log4j usage, especially jetty. This
+review has not revealed any vulnerabilities.
+{%- endtrans %}
+
+{% trans -%}
+It was also important to check all of our plugins. Plugins may bring in their
+own logging systems, including log4j. We found that most plugins also do not use
+log4j, and those that do did not use a vulnerable version of log4j.
+{%- endtrans %}
+
+{% trans -%}
+As of now we haven't found any dependency, plugin or app that's vulnerable.
+{%- endtrans %}
+
+{% trans -%}
+We bundle a log4j.properties file with jetty for plugins that introduce log4j. This
+file only has an effect on plugins which use log4j logging internally. We have
+checked in the recommended mitigation to the log4j.properties file. Plugins which
+enable log4j will run with the vulnerable feature disabled. As we cannot find any
+usage of log4j 2.x anywhere, we have no plans to do an emergency release at this 
+time.
