Summary
The PPWP – Password Protect Pages plugin for WordPress up to version 1.9.18 is vulnerable to PHP Object Injection via deserialization of untrusted input from the 'post_protection_roles' parameter. Authenticated attackers with Contributor-level access can inject a PHP Object. No known POP chain exists in the vulnerable software, but if another plugin or theme with a POP chain is installed, further attacks are possible.
Risk Assessment
If an additional plugin or theme with a POP chain is installed, an attacker could delete files, access sensitive data, or execute code, posing a serious threat.
Recommendation
Update the plugin to a patched version and remove unnecessary plugins and themes that may contain POP chains.

Original NVD description (English source)
The PPWP – Password Protect Pages plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.9.18 via deserialization of untrusted input from the 'post_protection_roles' vulnerable parameter. 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.
