CVE-2024-0900 is a missing authorization vulnerability in the Elespare WordPress plugin for Elementor, specifically in the elespare_create_post() function invoked via AJAX. The function lacks proper capability checks, enabling authenticated users with low privileges (subscriber-level and above) to create arbitrary posts. This vulnerability affects all versions up to and including 2.1.2. The CVSS 3.1 base score is 4.3, reflecting a medium severity impact primarily due to the ability to create content without proper authorization.

An attacker with subscriber-level access or higher can exploit this vulnerability to create arbitrary posts on the affected WordPress site. This could lead to unauthorized content injection, potentially impacting the integrity of the site’s content. There is no indication of confidentiality or availability impact. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict user roles to trusted individuals only and monitor for unauthorized post creation. Avoid granting subscriber-level or higher access to untrusted users. Review and harden AJAX endpoint permissions where possible.
