AI-suggested
Until an official fix is available, administrators should review installed plugins and themes for potential POP chain gadgets that could be exploited in conjunction with this vulnerability. Consider disabling or removing the crmperks Database plugin if not essential, or restricting access to the vulnerable functionality to trusted users only. Monitor vendor channels for updates and patches.
Description
The Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.4.7 via deserialization of untrusted input in the 'download_csv' function. 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.
