WPManageNinja disclosed a security incident in which an attacker compromised an old server that remained connected to its plugin update infrastructure after the company migrated its store and licensing system away from Easy Digital Downloads (EDD). For about five hours on July 31, the server distributed tampered versions of Fluent Forms Pro 6.2.7 and Ninja Tables Pro 5.2.11, including to sites with automatic updates enabled. WPManageNinja says around 295 customer accounts may have received the altered files, although 1,368 customers who downloaded either plugin on July 30 or 31 were notified because its logs could not determine exactly which copy each site received. Clean versions were released, the old server and routing were shut down, and affected users are being asked to reinstall the plugins and check their sites for signs of compromise.
