CVE-2026-40738

Name of the Vulnerable Software and Affected Versions Eldon versions prior to 1.4.2

Description The Eldon - Artist Portfolio WordPress Theme is susceptible to PHP Object Injection due to the deserialization of untrusted input. This allows unauthenticated attackers 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 other installed plugins or themes could enable the deletion of arbitrary files, retrieval of sensitive data, or remote code execution.

Recommendations Update to a version newer than 1.4.1.
