After weeks of testing, Joomla! Team yesterday announced the release of Joomla! 1.5.15. This version has taken 3 months to mature and finalize since Joomla! 1.5.14. It contains one moderate and one low priority security fixes as well as numerous bug and features patches.
Those two security issues are:
- Moderate Priority - Core - Front-End Editing: When logged into the front end with Author access, it was possible to replace an article written by another user.
- Low Priority - Core - XML File View: 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.
For the full list of other patches please see Joomla! 1.5.15 announcement. You can find download links there. If any issues come up after its release, you will be able to read about them at Joomla 1.5.15 Post-Release FAQs.
