Version 2.12.6 of Paid Memberships Pro is out with a very important security fix.

All versions of PMPro since 2.3 are vulnerable to the issue fixed in this release. The vulnerability allows malicious actors with no authorization to add new levels or change the details of existing levels, including the level price. With this ability, someone could change a level price to $0, allowing them to bypass your paywall or otherwise cause issues with your site.

Please update Paid Memberships Pro from the plugins page of your WordPress dashboard. You can also get the latest version of PMPro here. We recommend that everyone upgrade as soon as possible.

We have no reason to believe that this vulnerability is being abused widely, but to be sure your site was not impacted by this issue, double-check that your levels are all still configured as intended.

Thanks to Craig Smith and WordFence for the responsible disclosure of this issue.
