Base vector

Name of the Vulnerable Software and Affected Versions The Button plugin for WordPress versions up to, and including, 1.1.28

Description The issue is related to PHP Object Injection via deserialization of untrusted input in the button shortcode function. This allows authenticated attackers with contributor-level access and above to inject a PHP Object. While no known POP chain is present in the vulnerable plugin, the presence of one via an additional plugin or theme could enable attackers to delete arbitrary files, retrieve sensitive data, or execute code.

Recommendations For versions up to, and including, 1.1.28, update to a version that fixes the PHP Object Injection vulnerability to prevent exploitation. As a temporary workaround, consider restricting access to the button shortcode function until a patch is available.
