Unauthenticated PHP Object Injection in EasyMeals <= 1.5.1 versions.

AnalysisAI

Unauthenticated PHP Object Injection affects the Mikado-Themes EasyMeals WordPress theme through version 1.5.1, allowing remote attackers to inject crafted serialized objects that are deserialized by vulnerable PHP code paths. Successful exploitation can lead to high-impact compromise of confidentiality, integrity, and availability on the underlying WordPress site, though no public exploit identified at time of analysis. The CVSS 8.1 score reflects high attack complexity, consistent with the typical need for a usable gadget chain in the host WordPress environment.

Technical ContextAI

The vulnerability is a CWE-502 (Deserialization of Untrusted Data) flaw in the EasyMeals theme by Mikado-Themes, identified by CPE cpe:2.3:a:mikado-themes:easymeals through version 1.5.1. PHP Object Injection arises when user-controlled input reaches functions like unserialize() without validation, causing PHP to instantiate arbitrary classes and trigger magic methods such as __wakeup, __destruct, or __toString. In WordPress theme contexts these primitives are commonly chained with POP (Property-Oriented Programming) gadgets present in WordPress core, popular plugins, or PHP libraries, enabling outcomes like arbitrary file write, SQL injection, or remote code execution depending on which gadgets are loadable in the target environment.

RemediationAI

No vendor-released patch identified at time of analysis in the provided data; site operators running EasyMeals 1.5.1 or earlier should consult the Patchstack advisory at https://patchstack.com/database/wordpress/theme/easymeals/vulnerability/wordpress-easymeals-theme-1-5-1-php-object-injection-vulnerability and upgrade to a fixed release once published by Mikado-Themes. As compensating controls while a fix is awaited, deactivate and replace the EasyMeals theme with an unaffected theme (this will remove the front-end design and any theme-specific shortcodes), or place a WAF rule in front of WordPress that blocks request parameters containing serialized PHP patterns such as 'O:' or 'a:' followed by length-prefixed class names (note this may break legitimate plugins that pass serialized data). Where the vulnerable entry point can be identified from the advisory, restrict access to that endpoint via web server ACLs or .htaccess rules, accepting that this may disable affected theme functionality.
