Nonetheless, if you use the Tatsu Builder plugin, we strongly recommend updating to the latest version available, which is 3.3.13 at the time of this writing. Please note that version 3.3.12 contained a partial patch but did not fully address all issues.\n\nIf you know anyone using the Tatsu Builder plugin on their site, we urge you to forward this article to them as this is a large-scale attack and any vulnerable sites that are not updated and not using some form of a Web Application Firewall are at risk of complete site takeover.\n\nIf you believe your site has been compromised as a result of this vulnerability or any other vulnerability, we offer Incident Response services via Wordfence Care. If you need your site cleaned immediately, Wordfence Response offers the same service with 24/7/365 availability and a 1-hour response time. Both these products include hands-on support in case you need further assistance.\n\n\nSource:packetstormsecurity.com\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-02T01:01:49.102372Z"}
