Type:

CWE-502 Deserialization of Untrusted Dat

Description

The JS Archive List plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.1.7 via the &#39;included&#39; shortcode attribute. This is due to the deserialization of untrusted input supplied via the &#39;included&#39; parameter of the plugin&#39;s shortcode. 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. 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.
