As you may have heard, Google has discovered a flaw in the security protocol SSL 3.0, called POODLE. The security flaw concerns the protocol itself and has no connection to Klarna’s implementation. In fact, it affects all web-based services in the world.
Ends January 21
To address the problem Klarna will stop supporting SSL 3.0, January 21 at 10:00. For you as a WooCommerce Klarna payment gateway user, this means that your web host needs to support any of the subsequent versions for SSL 3.0. The first is called TLS (Transport Layer Security) 1.0 and was released in 1999.
No update of the module is required
Since any changes that may be needed are related to your hosting, no specific update of the Klarna for WooCommerce extension will be required.
The subsequent version of SSL 3.0 has been around for more than 15 years, so it is likely that you will not be affected at all by this change.
