<p>The Apache Struts group is pleased to announce that Struts 2.5.28.2 is available as a “General Availability”
release. The GA designation is our highest quality grade.</p>
<p>This release addresses Log4j vulnerability <a href="https://logging.apache.org/log4j/2.x/security.html#CVE-2021-45105">CVE-2021-45105</a>
by using the latest Log4j ver. 2.12.3 (Java 1.7 compatible).</p>
<p><strong>Please note, that the Apache Struts itself depends on the log4j-api package only, it’s users’ responsibility
to use a proper version of the log4j-core package!</strong></p>
<blockquote>
<p>Please read the <a href="https://cwiki.apache.org/confluence/display/WW/Version+Notes+2.5.28.2">Version Notes</a> to find more details about performed
bug fixes and improvements.</p>
</blockquote>
<p>Apache Struts 2 is an elegant, extensible framework for creating enterprise-ready Java web applications.
The framework has been designed to streamline the full development cycle, from building, to deploying,
to maintaining applications over time.</p>
<p><strong>All developers are strongly advised to perform this upgrade.</strong></p>
<p>The 2.5.x series of the Apache Struts framework has a minimum requirement of the following specification versions:
Servlet API 2.4, JSP API 2.0, and Java 7.</p>
<p>Should any issues arise with your use of any version of the Struts framework, please post your comments to the user list,
and, if appropriate, file <a href="https://issues.apache.org/jira/projects/WW/">a tracking ticket</a>.</p>
<p>You can download this version from our <a href="download.cgi#struts-ga">download</a> page.</p>

<h4 id="a20211212-2">12 December 2021 - Security Advice on Log4j 2.15.0</h4>
<p>The Apache Struts Security team would like to announce that all the users using the latest Struts 2.5.x series
should upgrade <a href="https://logging.apache.org/log4j/2.x/">Log4j</a> library to the latest <strong>2.15.0</strong> version which addresses
the Remote-Code-Execution vulnerability <strong>CVE-2021-44228</strong>.</p>
<p>This version of Log4j requires Java 8, while Apache Struts 2.5.x series is still using Java 1.7 and because
of that we cannot prepare a new patched 2.5.x version. Yet, in most cases this is a drop-in upgrade as Log4j 2.15.0
maintains binary compatibility with previous releases - once you are running on Java 8. In case you are not able
to upgrade Log4j, please use one of the described mitigations.</p>
<p>More information can be found <a href="https://logging.apache.org/log4j/2.x/#News">here</a>.</p>
<p><strong>All developers are strongly advised to perform this action.</strong></p>
