Description Elementra is susceptible to PHP Object Injection, a condition where an application deserializes untrusted input, allowing an attacker to inject a PHP Object. While no POP chain (a sequence of gadgets used to achieve code execution) is present in the software itself, the presence of a POP chain via another installed plugin or theme could enable an unauthenticated attacker to execute code, retrieve sensitive data, or delete arbitrary files.

Recommendations Update to a version newer than 1.0.9.
