CVE-2026-4123: CWE-862 Missing Authorization in rwelephant01 RW Elephant Rental Inventory
The RW Elephant Rental Inventory WordPress plugin up to version 2.3.13 contains a missing authorization vulnerability. The toggle_cache() function, accessible via an AJAX action, lacks proper capability checks and nonce verification. This allows authenticated users with Subscriber-level access or higher to toggle the plugin's cache setting via a crafted POST request.
AI Analysis
Technical Summary
CVE-2026-4123 describes a missing authorization vulnerability (CWE-862) in the RW Elephant Rental Inventory WordPress plugin versions up to and including 2.3.13. The vulnerability arises because the toggle_cache() function, hooked to the wp_ajax_toggle_cache AJAX action, does not perform capability checks nor nonce verification. As a result, any authenticated user with at least Subscriber privileges can toggle the plugin's cache setting on or off by sending a POST request to admin-ajax.php. This flaw could lead to unauthorized modification of plugin behavior but does not disclose sensitive data or cause denial of service.
Potential Impact
An attacker with authenticated access at Subscriber level or above can toggle the plugin's cache setting without proper authorization. This could impact the plugin's caching behavior, potentially affecting site performance or functionality. There is no indication of confidentiality or availability impact beyond this configuration change.
Mitigation Recommendations
No official patch or fix is currently documented. Users should restrict access to authenticated users with minimal privileges and monitor for unusual cache toggling activity. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
