We were recently contacted by Wordfence and Patchstack regarding PHP Object Injection vulnerabilities related to the use of unserialize() in Better Search Replace and WP Migrate, respectively. An additional internal review of all Delicious Brains plugins led to the security releases of the following five plugins and two-open sources libraries, which we recommend updating immediately.
Affected plugins and libraries
Better Search Replace and Better Search Replace Pro 1.4.5
