The Joomla developers have announced the release of version 1.5.13 of their content management system (CMS). The security update addresses a critical vulnerability in the Tiny browser included with the TinyMCE 3.0 editor that could allow files to be uploaded or removed without a user needing to be logged in. Version 1.5.12 is affected. Additional details, however, have not been provided.
A moderate cross site scripting (XSS) issue has also been fixed that could cause some files to miss the JEXEC check, causing scripts to expose internal path information to the host. All 1.5.x versions up to and including 1.5.12 are affected. The 1.5.13 update addresses both of the issues.
