AI-Generated

The Live Composer plugin for WordPress is vulnerable to PHP Object Injection due to the deserialization of untrusted input, affecting all versions up to 2.1.18. Authenticated attackers with contributor-level access can exploit this vulnerability if a vulnerable plugin or theme containing a PHP Object Injection (POP) chain is also installed, potentially leading to severe actions such as file deletion, data retrieval, or arbitrary code execution. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of exploitation.

Original NVD Description

The Live Composer – Free WordPress Website Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.1.18 via deserialization of untrusted input . This makes it possible for authenticated attackers, with contributor-level access and above, 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.
