Hi, There are several security bugs in Joomla 1.5 RC 1 : 1) An exploitable sql injection in the archive section . I sent the exploit to the joomla developer, but here I am not going to publish it :) 2) A XSS bug, again in the archive section . 3) Several full path disclosure bugs . Direct access to many .../tmpl/...php files, will expose the full installation path . Joomla has released a new version (Joomla 1.5 RC 2) . - Omid
