As much as we hate to spring another upgrade on you all so soon after the release of vBulletin 3.6.6, an XSS flaw was identified today and in order to maintain our commitment to fix security problems as soon as we become aware of them, we have to release 3.6.7 and a patch for older versions.

All versions of vBulletin 3.6 prior to 3.6.7 are vulnerable to the XSS. vBulletin 3.5.x and 3.0.x are not affected.

To minimize the pain of another upgrade, there are no changed templates since 3.6.6 and no database schema changes, so the upgrade should be as simple and quick as possible.

Since we have fixed several bugs since vBulletin 3.6.6 was released, these fixes are also incorporated in this version and include amongst others:

• RTL support for date picker popup
• Fixed HTML for archive forum lists
• MySQL error while merging users fixed
• Smilie parsing error fixed
• PHP 5.0.5 errors fixed
• Hard-coded image paths fixed

A complete list of bugs fixed in the 3.6 branch is available in the project manager.

Please accept our apologies for bringing out a new version just days after the previous release. We're sorry.

Fixing the XSS Bug

The XSS problem can be resolved in one of three ways.

1. Full Upgrade: The best way to fix the problem is to perform a full upgrade, downloading the complete 3.6.7 package from the vBulletin Members' Area and following the regular upgrade instructions. This is the only option that will not only fix the XSS issue, but will also apply all the bug fixes made since the release of 3.6.6.
2. Patch: A second option is to download the patch files either in the Members' Area or attached to this thread and upload them to your web server, overwriting the existing files.
   Patch file: 366_patch.zip
3. Plugin: The plugin system built into vBulletin 3.6 allows the problem to be fixed with a simple plugin. The install file for this plugin is also attached to this thread and is the easiest way to fix the problem, as it does not require you to upload any files via FTP. The plugin will be automatically removed when you perform your next full upgrade. You can install the plugin by following the instructions here.
   Plugin File: vb_calendar366_xss_fix_plugin.xml

Please note the following:

• The plugin can be used with any previous version of vBulletin 3.6
• The patch can only be applied to vBulletin 3.6.4, 3.6.5 or 3.6.6
• You may perform a full upgrade to vBulletin 3.6.7 from any previous version of vBulletin 3.
