Description Guilherme de Almeida Suckevicz 2020-11-05 14:01:16 UTC 
is_blog_installed in wp-includes/functions.php in WordPress before 5.5.2 improperly determines whether WordPress is already installed, which might allow an attacker to perform a new installation, leading to remote code execution (as well as a denial of service for the old installation).
