WordPress 4.4 update breaks itself with SSL certificate problem…
- http://myonlinesecurity.co.uk/wordpress-4-4-update-breaks-itself-with-ssl-certificate-problem-unable-to-get-local-issuer-certificate/
Dec 9, 2015 - "WordPress4.4 has just been released and it is highly recommended to update. BUT it is -broken- on many servers. The update will go OK -but- it will also update the SSL certificate bundle that WordPress uses to update itself, the themes and plugins. The certificate bundle appears to be damaged-or-incorrect and stops any WP updates. You will get a message saying http_request_failed: “SSL certificate problem: unable to get local issuer certificate” whenever you try to do anything involving WordPress updates, updating or installing themes or plugins or using Jetpack features like stats or sharing etc. The error screen will look something like this. It doesn’t matter what plugin or theme you try to update. the error message will be similar:
>> http://myonlinesecurity.co.uk/wp-content/uploads/2015/12/ssl-update-error.png
… found this post on WordPress support that does fix the problem. All my WP sites gave me the SSL warning until I used the certificate bundle from that post:
- https://wordpress.org/support/topic/cant-update-wordpress-ssl-certificate-problem-error14090086s
… until WordPress fixes/updates themselves, you should manually do this yourself…
WordPress could send out a hotfix of some sort now to make this update… - Derek"

WordPress plugin backdoor
- https://www.helpnetsecurity.com/2016/03/07/popular-wordpress-plugin-opens-backdoor-steals-user-credentials/
Mar 7, 2016 - "If you are one of the 10,000+ users of the 'Custom Content Type Manager (CCTM)' WordPress plugin, consider your site to be compromised and proceed to clean your installation up, Sucuri Security researchers have warned. After finding “a very suspicious auto-update.php file inside wp-content/plugins/custom-content-type-manager/ during the cleanup on an -infected- WP site, the researchers have begun digging, and discovered that:
• The file in question is a backdoor that can download additional files from a third-party domain, and save them in the plugin directory
• The CCTM plugin has been available for download from the official WP Plugin Directory for around three years, but hasn’t been updated in the last 10 months. But, some two weeks ago, a new developer (“wooranker”) started -adding- “small tweeks by new owner” and “bug fixes”… Users who want to keep using the plugin are advised revert to using version 0.9.8.6. and to -disable- automatic plugin updates."
