What is CVE-2024-13770?

CVE-2024-13770 is a high-severity unsafe deserialization vulnerability in ThemeREX Puzzles | WP Magazine / Review with Store WordPress Theme + RTL, published on 13 Feb 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The Puzzles | WP Magazine / Review with Store WordPress Theme + RTL theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.2.4 via deserialization of untrusted input 'view_more_posts' AJAX action. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. The developer opted to remove the software from the repository, so an update is not available and it is recommended to find a replacement software.
