 "title": "Ninja Tables <= 5.5.0 - Authenticated (Administrator+) PHP Object Injection via Imported Row Settings",
 "description": "The Ninja Tables plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 5.5.0 via row settings restored from an imported Ninja Tables JSON file, which were stored verbatim and later read with maybe_unserialize() when the table is rendered. This makes it possible for authenticated attackers with administrator-level access, such as site administrators on a multisite network, to inject a PHP object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.",
