vBulletin Security Patch for vBulletin 4.1.12 for Suite & Forum - 04/23/2012

vBulletin has released a security patch to improve the security of the vBulletin 4 MAPI for 4.1.12 Suite & Forum as the result of a recent internal security review. Although no exploits have been reported, we urge our customers to upgrade as soon as possible.

The changes do not affect vBulletin 4.0.0 - 4.1.1.

This patch has been issued for vBulletin 4.1.12. A separate set of patches have been issued for vBulletin 4.1.2 - 4.1.11.

The MAPI security improvements have been added for vBulletin 3.x with the release of 3.x MAPI 1.4.3.

To improve the security of your vBulletin 4 installation, please download the patch from the members area of vBulletin:

In addition to the security improvements, we've resolved the following 4.1.12 issues.
  • VBIV-14742 - Push notifications broken in FR 4.1.12 add-on.
  • VBIV-14685 - Tag in static page cause Fatal error on page with General Search widget set to return Static Pages
  • VBIV-14663 - Quoting doesn't work in the mobile style
  • VBIV-14660 - Static HTML in CMS always displays all content
  • VBIV-14754 - unset($VB_API_PARAMS_TO_VERIFY['vbseourl']) to match vB3 MAPI change.
  • VBIV-14681 - HTML is stripped from article previews
  • VBIV-14667 - Category pages do not load if using basic/advanced friendly URLs

The upgrade process is slightly more complicated for this patch level release.

  1. Download PL1 for vBulletin 4.1.12 from
  2. Upload the patch do your server.
  3. Unzip the patch to your vBulletin 4 install directory. (Ex. /var/www/html/myforum)
  4. Run ./install/upgrade.php. (Required for 4.1.12.)
  5. Download the "API-Log-Clean.xml" attached to this thread. (Included in the do_not_upload folder for full installs.)
  6. Import "API-Log-Clean.xml" using the "Manage Products" interface in the "Plugins & Products" section of your Admin CP. The cleanup script will run on install. AdminCP -> Plugins & Products -> Manage Products -> Add/Import Product
  7. Delete "API-Log-Clean" using the "Product Manager" option in the "Plugins & Products" section of your Admin CP. (Optional. The product is automatically disabled after the script runs.)
