Short explanation
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress up to version 6.3.2 is vulnerable to PHP Object Injection via deserialization of untrusted input during ZIP template import.
Authenticated attackers can leverage POP chains present in other plugins or themes to retrieve sensitive data, delete files, or execute code.
What should be done?
- Follow the vendor advisory for updates
- Review plugin access permissions and configurations
- Remove unused plugins and themes
Chain of evidence and sources
Kirki eklentisinin 6.3.2 ve önceki sürümleri ZIP şablonu içe aktarımında PHP Object Injection zafiyeti içermektedir.
Varsayılan KIRKI_USERS_DEFAULT_FULL_ACCESS yapılandırması nedeniyle istismar Editor seviyesinde de mümkündür.
Zafiyetin etki yaratması için hedef sistemde POP zinciri içeren başka bir eklenti veya tema gereklidir.
Show the technical text from the sources
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.3.2 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-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. By default, Editor-level users are granted FULL_ACCESS to the plugin's import endpoint via the KIRKI_USERS_DEFAULT_FULL_ACCESS configuration, meaning exploitation is possible at Editor privilege level rather than being restricted to administrators alone.
