MyBB 1.4.2 is a general maintenance release and a security update to the MyBB 1.4 series. It fixes a few high risk and several medium risk and low risk security vulnerabilities. We recommend everybody upgrades to this release immediately or patch their boards with the manual patching instructions below.

This release comes as the result of a professional security audit performed by GulfTech. (As can be verified here) As this security audit cost us a considerable amount out of our own pockets, we ask that if you haven't already and have a few spare dollars to spare that you consider donating to MyBB.

These vulnerabilities affect MyBB 1.4.1 and several affect previous releases of MyBB 1.2 (including 1.2.14). Older versions of MyBB may also be affected. Please see the post below for upgrade instructions for 1.2.14.

MyBB 1.4.1 to MyBB 1.4.2 Patch
This patch is only for users running MyBB 1.4.1. If you are running an older version of MyBB then please download MyBB 1.4.2 from the MyBB site and update to it.

Please download the attached ZIP archive and replace the files in your forum directory with those from the ZIP archive.

If you wish to manually patch your board please download "mybb_1401_patches.txt" and follow the instructions in that file.

For the upgrade of 1.4.1 to 1.4.2, the upgrader IS required -- this is so that templates may be updated. The manual patch set instructions only fixes the high risk and medium risk vulnerabilities and is only made available to temporarily secure your forum until you have time to run the complete upgrade. We strongly recommend updating as soon as possible.

Reporting MyBB security vulnerabilities
If you think you've found a vulnerability in MyBB, we advise you not to publicly post it on these forums or publicly release information about it elsewhere until we've had time to prepare and release a patch.

As always, you can send through security related messages on the MyBB website from the Contact Us page.

MyBB 1.2.14 Patch
This patch is only for users running MyBB 1.2.14 or any previous release of the MyBB 1.2 series.

Please download "mybb_1214_patches.txt" attached to this post and follow the manual patching instructions.

Please note all users of the 1.2.x series are urged to upgrade to the latest release of MyBB. (1.4.2)

Upgrading from 1.4.1
When upgrading from 1.4.1, you will not lose any custom themes, plugins or language packs which you may have installed.

Follow the general [Wiki: Upgrading] (Broken link, head over to docs.mybb.com instead) guide outlined on the MyBB Wiki to complete the upgrade process. You may download a ZIP archive of changed files in the first post.

You must then check for modified templates using the instructions in the next post.

Upgrading from other versions
If you are upgrading from a version earlier than 1.2 then you will lose your custom themes, templates and language packs due to the number of changes between your version and the 1.2 series.

Before you attempt to upgrade, ensure you have a database backup and a copy of the files currently in use on your board. This is so you can revert back to your earlier version if you need to or something goes horribly wrong with the upgrade process.

Please use the full MyBB 1.4.2 package for the upgrade process, available at http://www.mybboard.net/downloads . The changed files package on this thread is only for users upgrading from 1.4.1.

Follow the general [Wiki: Upgrading] (Broken link, head over to docs.mybb.com instead) guide outlined on the MyBB Wiki to complete the upgrade process.

Theme and template changes
Using the "Find Updated" link under the "Templates" page in the Admin CP you can find a list of the templates that have changed in this release that you've got one or more custom copies of.

After identifying changed templates using the tool you can either revert your custom template to the default (delete it) or use the "diff" tool to perform a difference analysis on your custom template and the default.

A revert for this release is not required so your custom version of the template should work perfectly fine.

Template changes
Since MyBB 1.4.1 the following templates have had changes to them:

• private_send
  
• polls_showresults_resultbit
  
• showthread_poll_resultbit
  
• search
  
• postbit_attachments_attachment_unapproved
  
• calendar_addevent
  
• calendar_eventbit_private
  
• calendar_eventbit
  
• calendar_editevent
  
• calendar_move
  
• warnings_warn_pm
  

Language file changes
Since MyBB 1.4.1 the following language files have had changes to them:

• admin/config_settings.lang.php
  
• showthread.lang.php
  

Either update your language packs to include the changes in these files or revert to the standard English language pack.

Plugins
Your MyBB 1.4.x plugins will work correctly with 1.4.2 without any updates.
