 "title": "UpdraftPlus <= 1.26.8 - Unauthenticated SQL Injection via Database Restore",
 "description": "The UpdraftPlus plugin for WordPress is vulnerable to SQL Injection via the database restore process in all versions up to, and including, 1.26.8. The cause is insufficient parsing of backed-up SQL when splitting it into statements: a line was treated as a complete statement when it simply ended in a closing parenthesis and delimiter, without checking that quotes and brackets were balanced. This makes it possible for unauthenticated attackers who can store a large (over 1MB) database value with crafted content, for example through a site feature that accepts visitor-submitted data, to have arbitrary SQL queries executed when a site administrator later backs up and restores the site. This could lead to full site compromise, such as the creation of administrator accounts.",
