Der Editor ist an sich recht schlank und schön. Weil es ein Browser Plugin ist, der beim Client läuft und nicht alles aus dem Web geladen werden muss. Also halb so schlimm.
It is possible to read the contents of an extension's XML file and find the version number of the installed extension. This could allow people to exploit a known security flaws for a specific version of an extension.
All 1.5.x installs prior to and including 1.5.14 are affected.
Turn on Apache mod_rewrite and configure your .htaccess file to filter out XML files. In the htaccess.txt file shipped with version 1.5.15, lines 35-39 contain example code that will deny access to XML files. You can incorporate this code (or similar code) into your .htaccess file. Be sure to test that it does not cause problems on your site.
