More information on the 3.4 release (and the 3.x platform in general) can be found in the 3.x Documentation Preface.

DSpace 3.4 contains security fixes for both the XMLUI and JSPUI. To ensure your 3.x site is secure, we highly recommend all DSpace 3.x users upgrade to DSpace 3.4.

We also highly recommend removing any  "allowLinking=true" settings from your Tomcat's <Context> configuration. Previously our installation documentation erroneously listed examples which included "allowLinking=true", while the Tomcat documentation lists it as a possible security concern. The XMLUI Directory Traversal Vulnerability (see below) is also exacerbated by this setting.

If you are running an older, unsupported version of DSpace (1.x.x), we highly recommend upgrading to DSpace 3.4, DSpace 4.3 or DSpace 5.1 to ensure your site is secure. Several of these security vulnerabilities also affect sites which are running DSpace 1.x.x releases. Per our DSpace Software Support Policy, all DSpace 1.x.x versions are now End-Of-Life.

If you are considering an upgrade from DSpace 1.x.x, note that, as of DSpace 5, your existing data (i.e. database contents, search/browse indexes) will now be automatically upgraded from ANY prior version of DSpace. Therefore, you may wish to consider upgrading directly to DSpace 5.1, as the 5.x upgrade process is simplified.



DSpace 3.4 is a security fix release to resolve several issues located in DSpace 3.3 or below. As it only provides security-fixes, DSpace 3.4 should constitute an easy upgrade from DSpace 3.x for most users. No database changes or additional configuration changes should be necessary when upgrading from DSpace 3.x to 3.4.

This release addresses the following security issues discovered in DSpace 3.x and below:
